1.2 MODEL PSIS SPECIFICATIONS 1.1 DESCRIJYrION Outputs One powered channel, CHI, (audio + DC + 200 ohm/400 ohm 10% termination}, and one passive chan- nel' CH2, (audio + 200/400 ohm 20% termination}. The Model PS 15 Power Supply is designed to work within the TW Intercom System. The PS 15 is suitable for small to medium sized TW Intercom Systems. Output Voltage No Load Full Load 32.0 +2.0. -1.0 volts 24.0 volts. nominal The unit is self-contained and features two-channel opern- tion: one "wet" channel with 24 to 32 volts DC and one "dry" channel without voltage potential. Each channel provides an audio termination impedance of 200 or 400 ohms (switch selectable). Output Impedance 200 or 400 ohms 20%. switchable. On powered channel. 200 ohms. nominal. is maintained from 18.0 to 33.0 volts. This power supply allows speech signals and DC to exist on the same wire (Channel I). The power supply's outputs are protected against short circuit conditions with recovery being automatic and instantaneous. Output Current S13nd'Jfd Option *p Option (234 V) #D Option (IOOV) Fault Current .9 ampere at 21/+4-2 volts. DC .9 ampere at 21/+4-2 volts. DC .8 ampere at 21/+4-2 volts. DC 1.5 amperes at 0.0 volts. DC A single PS 15 Power Supply can power 6 to 30 user stations (depending on model and combination -see specifications). Signal Level Nominal Maximum If still more user stations are needed, two PS 15 Power Supplies can be coupled together to double the powering capability: a 1/4-inch 3-circuit phone jack is available on each power supply for this purpose. This connector can also be used as a one-way output port when monitoring or recording the intercom audio signals. 2.0 volts peak to peak 5.0 volts peak to peak Frequency Response 100 hertz to 20 kilohertz +1, -5 dB When two PS15 supplies are combined. toggling a rear pmlel switch on each supply will keep the audio level constallt. Two PS 15. s can power as many stations as a PS31 (with DC load evenly distributed between the two supplies). Since the PS31 supplies more voltage than the PS15 under full load. the PS31 is better suited to power a large system spread over a large area.

at 800 milliamperes when connected in series, but with

100 volts at the primaries the output voltage is 26 volts. 2.1 MECIIANICAL INSTALLATION Note: The European version of the Model PSIS is equipped with a special three conductor European power cord / plug set. The plug is the a CEE7n style rated for 234 volt /10 to 16 ampere service. The European version is also equipped with a metric fuse holder and an internationaJ S by 20 millimeter fu~. The Model PSl5 can be installed in 3 ways: a single unit mounted in a half rack space using an optional Modcl MCP2 Kit for rack mounting a single unit; or two PSl5 supplies mounted side by side using the optional MCPl Kit for rack mounting two units side by sidc; or frce standing using the optional MCP8 Kit for adding side channels for non-rack mounting portable 1,Ise. 2.4 ELEcrRICAL PERFORMANCE AND LOADING 2.2 OUTPUTS Located on the back panel are the outputs. The PS15 is designed to accept A3F 3-pin female connectors. The first table on the next page shows operating distances versus model numbers for the PS15 power supply. The second table on the next page shows the maximum number of user stations that the PS15 can sustain. For combinations of stations, multiply the current values in the first table times the number of units of that type. The sum of all the currents should be less than 1 ampere for the PS15. 2.3 POWER and INPUT POWER SELECTION 2.5 TANDEM OPERATION Two Model PS 15 power supplies can be used in tandem to double the number of stations that can be powered. First, the stations are divided between the supplies. Then, a stereo patch cord is plugged into the stereo jack on the rear panel of each supply. The DUAL/NORMAL switch is set to DUAL. This switch corrects the halving of the impedance of two supplies in parallel by doubling the impedance of each supply from 200 to 400 ohms. The line signal levels are maintained because the net impedance is now 200 ohms. The power cord is attached to the rear panel. Power selection is normally done at the factory. If field change of the input mains voltage is required, disconnect the power, open the case, and set jumpers as follows (using layout diagram on page 10): For 117 V AC operation, T1 is Signal Transformer LP56-425 or equivalent; install W1, W2, W4, and W6, remove W3 and W5. * (Standard-American ] For 234 V AC operation, T1 is Signal Transformer LP56-425 or equivalent; install W3, W4, and W6, remove W1, W2, and W5. * [*P Option-European] For 100 V AC operation, TI is Signal Transformer LP30-800 or equivalent: install Wl, W2, and W5, remove W3, W4, and W6. ** [#D Option-Japanese) The fuse must aJso be changed to the rating shown on the rear panel. 2.6 AUDIO OUTPUT I INPUT The AUDIO COUPLING CHI-CH2 jack on the rear panel provides an unbuffered, unbalanced audio output for each of the two channels. The level ranges from -10 dBu to 0 dBu. An isolation transformer is recommended to prevent a ground loop between the intercom system common and other grounds. .Transformer LP56-425 is a dual primary, dual secondary transformer. The primaries are 115 volts each. The two secondaries are rated 28 volts at 850 milliamperes when connected in parallel. For 115 volt operation, the primaries are in parallel, and the secondaries are in parallel. For 230 volt operation, the primaries are in series, and the secondaries are in parallel. The AUDIO COUPLING jack may also be used to input a signal into the system. Use at least a 2.2 kilohm resistor in series with the signal source to prevent loading of the RTS Systems intercom line. Use an audio isolation tranformer to prevent ground loops. ..Transformer LP30-800 is a dual primary, dual secondary transformer. The primaries are normally rated 115 volts each, but jn this case will be operated at 100 volts each. The secondaries are normally rated at 30 volts Page 5
