This product is not designed to be used in applications such as life support systems wherein a failure or malfunction could result in injury or death) Technical description - a unique mechanical concept The Camtec CPS-EX models are high-precision industrial power supplies „Made in Germany“. These power supplies are designed for scalable power systems. For more than 25 years the Camtec Power Supplies manufactures high-end switch mode power supplies in Germany. A field breakdown of below 0,004% over a 10-year period under review approves our ambitious quality concept. Each manufactured Camtec product passes several 100% random tests for each detailed function and a full-load Burn-In test. Although it is not required from the safety norms our production applies a routine safety test to each manufactured device, even if it is an extra low-voltage model. The components in the assembled device pass stress aging to achieve an even level and to prevent from delayed failures. Our internal product engineering guidelines provide a clear target: Camtec product reputation must say „mount and forget“. Quality is never a mere promise for our team. The CPS-EX power supplies provide low noise and ripple, a very quick programming, and a precise setting at high load changes. With an efficiency of 92-94% and a power factor of 0.99, the devices are highly energy efficient. Equipped with high-end capacitors of outstanding lifetime our power supplies guarantee a very long and reliable operation time. The circuit design of the CPS-EX Series allows cope playing with complex loads. The internal protection circuits protect the power supply and the connected system, even in exceptional situations. The CPS-EX series is protected from high transients by strong filters with high energy efficiency. All inputs and outputs and the interface are electrically isolated. The design specifications call for the highest standards of safety and interference suppression. The device was developed in accordance with the requirements of EN61010-1, EN61010-2-201, EN62368-1 and the EMC standards EN55032 conducted Class B, radiated Class A. The mechanical design of the CPS-EX2000 device series is unique. It is the first power supply line in the world market, which can be flexibly adapted to any installation situation. The forced air-cooling system with monitored and load-dependent variable fan control, allows a detached position in the system. By simple and cost-effective wall brackets the device can be integrated in any position in 90° increments. Unlike comparable power supplies Camtec comes here for the first time to let the system integrator completely free hand. The cooling concepts for supply and exhaust air can be designed to completely remove the heat dissipation from the cabinet. Complex and expensive air-conditionings for switch cabinets can be reduced to a minimum or even eliminate. Brackets for air channels are available as an option. In selecting the fan, as with all our power supplies, in our opinion we use with the German manufacturer EBM Papst the highest quality and most reliable devices in the world market. The installation of the power supply in a 19" subrack is guaranteed in the simplest way. Again, our engineers have decided to offer a completely open and flexible system. The optional front panels allow the power supplies the use in either a 2U or 3U subrack. In this way we can realized 6kW in 2U-rack and up to 10kW in a 3U-rack with the CPS-EX2000 models. With Zero-Stacking the series allows scalable high-power DC source in a comparable small 19-inch rack unit. For power applications with high dynamic range above 10kW we recommend contacting our support team. As accessories for the CPS-EX Camtec provides matched 19 "subframes. Our subracks deserve the name of a carrier, because they really are extremely stable made of stainless steel. The power supplies have nickel- plated steel pins to position the power supplies in the subframes. The so married together systems withstand the toughest conditions. All mechanical connections in the power supplies or on the racks are constructed with A2 or nickel-plated screws, so that they provide maximum protection against corrosion and conductivity.

This product is not designed to be used in applications such as life support systems wherein a failure or malfunction could result in injury or death) Features Idling behavior The CPS-EX Series is permanently open-circuit proof. When an output voltage is preset it comes stable. If a load is switched suddenly, the unit stabilized within <1ms. An overshoot of the output voltage is irrelevant. Start behavior The power supply has a start delay of 1s to stabilize all measuring circuits for the interface messages accurately. The power supply starts with a ramp (soft start) of 100ms. The output voltage does not overshoot - regardless of whether a load is connected or not. Galvanic isolation and insulation The switching power supply is galvanically isolated between the input and the output. All major digital inputs and outputs of the interface are electrically isolated. V programming (Ureg) The output voltage of the CPS-EX power supply can be adjusted by a control signal. The setting is linear to the input signal. The power supply operates data stable even at all output voltages. C programming (Ireg) The output current of the CPS-EX power supply can be adjusted by a control signal. The setting is linear to the input signal. The power supply operates data stable even at all output currents. V Monitor (Umon) The power supply provides real-time monitoring of the output voltage. It is the exact and real value at the output terminals. If the sense line is used, the real value is measured directly at the load. The latency signal preset to the measured value is negligible since the control circuit is constructed completely analogously. C Monitor (Imon) The power supply provides real-time monitoring of the output current. It is the exact and real value at the output terminals. The latency signal preset to the measured value is negligible since the control circuit is constructed completely analogously. Constant Voltage or Constant Current Mode (CV/CC) The device can be operated as a DC voltage source or a constant current source. The operating mode is signaled on the interface. Auxiliary Voltage (AUX) The devices feature a 12V / 500mA auxiliary voltage to operate external peripheral. Potentiometer Internal Control (Uadj/Iadj) If the power supply shall only set with the built-in internal potentiometers, the use of the internal reference voltage is possible. The power supply requires no external signals and can operate completely autonomously. Potentiometer External Control (Uadj/Iadj) If the power supply shall only set with external potentiometers, the use of the internal reference voltage is possible. The power supply requires no external signals and can operate completely autonomously. Sense Mode The power supply has a sense mode to compensate for voltage drops of 2V per load line. Fuse Mode The unit can be operated in fuse mode. In the fuse mode, the unit is turned off and locked when it was more than 5 seconds in constant current mode to protect a connected defect load. The lock can be controlled remotely or repeal by disconnection from the mains again. Continuous Mode The unit can be operated in continuous mode. In the continuous mode, the power supply provides constant current mode in a continuous flow and no ticker-operation. Master-Slave Mode (Ureg-OUT/Ireg-OUT) The master-slave mode can be defined in the parallel operation. One device can be set as the master, the other involved network units act as a slave and the setting signals follow current / voltage, which are commanded by the Master. This ensures that all devices are operated synchronously. Current Share Bus (CS) In parallel operation, the involved network components communicate with each other and share the total power evenly to each other. Remote Shutdown (SD) All CPS-EX devices have a remote shutdown (open collector or switching contacts). Inhibit Mode (Interlock) The inhibit circuit reliably prevents unintentional starting of the power supply. The control loop is internally locked. Since this blocking is done progressively it is active even when the control signal, is missing due to a cable break or temporarily suspend. A premature restart of the power supply is prevented. The inhibit input can be connected to a relay or switch. If the contact is interrupted, the power supply is switched off. If the contact is closed again, the power supply restarts. DC and AC Fail By DC-fail the power supply reports that the power output is disabled. By AC-fail the power supply reports an AC undervoltage. Both signals have separate outputs. Each of them can be selected between NO and NC. Over Voltage Protection (OVP) On the interface is a message signal. Until the abolition of the fault the device switches off. Over Current Protection (OCP) On the interface is a message signal. Until the abolition of the fault the device switches off. Temperature Control (TEMP) The operating temperature of the power supply can be monitored via a signal applied to the interface output. Temperature Alarm (TA) If the device is in the critical range, a warning signal is applied to the interface. Over Temperature Thermal Shutdown (OT) The device has a thermal monitoring: shutdown with automatic restart. The OT signal is applied to the interface. Fan Failure Monitoring (FF) If it comes to a fan failure or blocking, a signal is applied to the interface. The speed signal of the fan is monitored. Thus, even a creeping fault is detected at an early stage and there is a warning long sold separately in front of a fan failure. 3D Heat Dissipation Our aligned and controlled heat dissipation design opens possibilities that are formerly being reserved to custom design power supplies: Steplessly hard mount of the CPS-EX2000/3000 power supply modules in a 3D-room. In practice that means that one can mount the modules into every angle imaginable. Our 3D heat dissipation (3D-HD) ensures optimal cooling in each mounting position you may consider. Design-to-Service: Most recorded failures in the field concern the signal interface of a power supply. Camtec offers new concept of design-to-service that allows the customer easily to exchange the interface himself in the field. The analogue and digital interfaces apply plug & play self calibrating and can be used independent from the model CPS-i/EX/EP 2000 & 3000 Thus, system down cost is being reduced and only a small amount of spare parts need to be stocked by the customer.

Programming/Monitoring V/C Analog Interface (Ureg-IN/Ireg-IN) (Umon/Imon) The standard programming of the CPS-EX Series is an analog interface. The output voltage is linearly proportional to the adjusted analog control signal. The monitor signal is analog linear to the output voltage. The monitor signal for current and voltage is the real value that is measured directly at the output of the power supply. If a sense line is connected to compensate for the voltage drop across the load lines, the monitor signal is exactly the value that is measured at the connection point of the sense line. The description of the power supply in the sense operation is carried out in a separate section. The analog inputs and outputs are non-floating. The mass is connected to the DC negative output. The burden of the control voltages is 1MΩ. The latency to full compensation of V/C on the interface from 0- 100% is 15ms for all CPS-EX models. Programming V/C via Potentiometer (Uadj/Iadj) – Stand Alone Operation The power supply is equipped with 2 potentiometers Uadj and Iadj for setting voltage and current. Connect each Uadj and Iadj of CON3 to the inputs Ureg-IN and Ireg-IN. If one of the two potentiometers is not used, the other value can still be programmed via the interface. In such case, only the control signal 0-5V can be used. Fuse Mode The Fuse Mode can be used mode to prevent a major damage to a defective load. Fuse Mode can be activated via the associated switch S12 DIP switch. If the device is in the Fuse Mode (DIP switch S12=0), the device switches off when the constant current operation is taking longer than typ. 5s. The red OCP LED flashes with a period of 0,4s. The PSU is locked. The interlock can be canceled by the power supply is either switched off by the mains input, SB or SD contact for a moment. Continuous Mode If you select Continiuous Mode at DIP switch S12 (DIP switch S12=1), the device provides continuous power. It also applicable in the Constant Current Mode. Factory setup = Continuous Mode

This product is not designed to be used in applications such as life support systems wherein a failure or malfunction could result in injury or death) Over Load Behaviour The CPS-EX changes from the standard operation mode into the high current mode when high and quick overload occurs. Thus, it provokes a restart after a 30ms break and delivers continuous current to the output. This special behaviour is a protection for the power supply and for the connected load. Compensation of Load Line Drop Voltage (Sense ++/--), standard operation mode The CPS-EX power supply has a Sense Mode to compensate for the voltage drop over long load lines. The compensation amounts to a maximum of 2V per load line. Under certain circumstances, it can be expected to apply more complicated external interference suppression. If sense is not used, CON4 Sense +/+ and Sense -/- shall necessarily be connected by short bridges to the power outputs (factory setup). Sense operation: Remove the bridges between Sense +/+, Sense -/- and the power outputs. Connect the sense lines directly to the load. It is irrelevant which of the local connections Sense +/+ and Sense -/- are applied. Pay attention to the polarity of plus and minus of the load to prevent damage to the power supply. To avoid interference, twist the sense lines. To reduce inductive effects, we recommend that the load lines position is close to each other. To supply a pulsating load, the use of an electrolytic capacitor and a cermic capacitor has proved. The internal Over Voltage Protection (OVP) of the power supply controls the DC power directly to the DC output terminals. In case of an error the OVP acts automatically (see OVP values corresponding table). Operating in the sense mode requires that the maximum output voltage will not be exceeded. Maximum 2V per load lead can be compensated. The voltage drop in the load lines decreases the maximum output voltage rating. Example of a 30V unit: if the total voltage drop in the load leads is 2V you must subtract this value from the maximum programmable output voltage 30V – 2V = 28V maximum available voltage at the load. The sense terminals are directly connected to the power outputs. Lokal Sensing Remote Sensing (factory setup) (twisted sense lines) WARNING! PROTECT TO MIX UP SENSE CONNECTIONS. THIS COULD CAUSE SERIOUS DAMAGE TO THE DEVICE. Compensation of Load Line Drop Voltage (Sense ++/--) battery charger operation mode Remote Sensing as a battery charger If the CPS-EX power supply unit is used as a battery charger, it is recommended to refrain from sensing. It can lead to severe damage to the power supply, if the polarity of the sense line is confused (field experience: such error often occurs when system service is required, e.g., when the batteries are changed). If it is necessary to use sensing, proceed as described in the figure below. Proven approaches are 250mA for the fuses and 3...5A load capacity of diodes.

This product is not designed to be used in applications such as life support systems wherein a failure or malfunction could result in injury or death) Master-Slave Mode (Ureg-OUT/Ireg-OUT) The CPS-EX power supplies offer the possibility of Master-Slave operation. To increase the output current, up to 5 units of the same type and output voltage can be connected in parallel. One device takes over the function of the master, the other devices assume the slave function. The Current Share Bus (CS) marries the involved power supplies together. The CS bus allows a symmetrical current distribution in parallel operation of several identical CPS-EX units. Define a power supply as the master. Set S11=0 for all the involved units. The signals of the interface are looped together. Connect Ureg-OUT and Ireg-OUT of the master to Ureg-IN and Ireg-IN from to slave. Connect the corresponding Ureg-OUT/Ireg-OUT from the slave to the next slave, etc. All the monitoring signals of each power supply are still available. Current Distribution in Parallel Mode (CS), CSB Current Share Bus In parallel operation, a uniform current distribution between the participating power supplies is important. To prevent one of the power supplies going early into the current limitation and display error message. An uneven load and thus premature aging of the participating devices is prevented. Connect CON3 contact 5 (CS) to contact 13 of the slave. Are other devices involved in the parallel operation, you may grind the CS bus through from unit to unit. The current division between the devices will be performed automatically. The accuracy of the current distribution is ±5% at Iout ≥ 0,5 x Iout max. Derate the total output current by 5% to prevent unit overload condition (signaling). External Shutdown (SD) The power supply is set to the Shutdown mode, when the control input is either shorted via a relay contact, a switch contact or an NPN transistor with open collector (voltage drop <1V, current typ. 1,5mA). Alternatively, a voltage of 10 to 30V (typ. 12V/1.5mA, 24V/5.5mA) can be applied. If the shutdown repeals the power supply starts with a delay of 35ms. Using the soft start, the current and the voltage rises within 100ms continuously to the default set values. Between control input SD and power output is a reinforced Isolation of max. 400Vdc and a basic isolation of max. 600Vdc working voltage. Standby (SB) The power supply is switched to standby mode when the control input is shorted optionally via a relay contact, a switch contact or an NPN transistor with open collector (voltage drop <1V, current typ. 1.5mA). Alternatively, a voltage of 10 to 30V (typ. 12V/1.5mA, 24V/5.5mA) can be applied. If the standby repeals, the power supply starts with a delay of 500ms. Using the soft start, the current and the voltage rises within 100ms continuously to the default set values. Between control input SB and power output is a reinforced Isolation of max. 400Vdc and a basic isolation of max. 600Vdc working voltage.

This product is not designed to be used in applications such as life support systems wherein a failure or malfunction could result in injury or death) Inhibit / Interlock (INH) The power supply is equipped with a control input Inhibit (INH) to interlock a DC-shutdown of the power supply. For the nominal operation of the power supply the connections of the control input "INH" must always be short-circuited. The power output is switched off as soon as the connection between the contacts of the control input INH is interrupted. If Inhibit is repealed, the power supply starts with a delay of 35ms. Using the soft start, the current and the voltage rises within 100ms continuously to the default set values. Between the INH contacts applies a current of typical 2mA. ! Warning against damage in case of incorrect connection assignment Never apply any external voltage to the control input INH. Never connect a resistor to the INH interface. The INH can only be connected to a floating contact (e.g., mechanical switch or relay).

This product is not designed to be used in applications such as life support systems wherein a failure or malfunction could result in injury or death) Open Collector Circuit Interface Between all open collector outputs and the power output is a reinforced isolation of max. 400Vdc and a basic isolation of max. 600Vdc working voltage. (Note: this applies to all signals from CON1 and CON2, regardless of whether they are designed as open collector, or not) Series Operation Two or more units of the same model and output voltage can be operated up to a total voltage of 600Vdc in series (not applicable to EN62368-1). Due to the dielectric strength of the internal components used, only the models with an output voltage of 48Vdc and later are approved for series operation. Other power supplies are not approved for series operation above 60Vdc. If the units are remotely controlled via the analog interface it is compulsory to use a potential-free control voltage! Parallel Operation & N+1 Decoupling To increase the overall power of the power supply, up to 5 units of the same model with the same output voltage may be operated in parallel. We recommend using a busbar for the DC power connector. Make sure that the cable lengths and cable cross-sections of all power supplies to the busbar or to the star point are identical. Allow proper connection for low contact resistance. If you want to use the sensing function, connect it also to the star point or busbar. To avoid measurement errors, select the line length from the neutral point or from the busbar to the load as short as possible and use the maximum possible conductor cross-section. The CPS-EX models have no internal O-ring diode, to operate the devices N+1 redundant.
