The 3 control outputs enable the dimming of different series of underwater LED lights by using of one push-button switch. FEATURES • 3 Control Outputs • Adjustable PWM Frequency • Wide Range Power Supply • Low Power Consumption • Polarity Protection • Transient Protection • Short Circuit Output Protection • Simple Installation PRECAUTIONS • The PWM Dimmer has to be installed and used in accordance with the instructions of this manual only. • The power supply has to be disconnected before installation. • Avoid installing the PWM Dimmer in extremely hot places and near appliances generating strong magnetic fields. • Do turn power off immediately and refer servicing to qualified service personnel if the PWM Dimmer does not operate normally following the operating instructions. 4 CONTROLS AND CONNECTORS PWM Dimmer MDU13 (1) CONTROL The 2-pole terminal block connector to connect push-button switch to operate with dimming function. (2) DC IN Terminal-block connector to connect 12-24Vdc power supply. (3) CH-1 Control output to connect the +Control (P) and GND Control (-) wires of single-color Equator / Conus / Convex / Plaque series. The control output to connect the +Control (P) and GND Control (-) wires of RED or WHITE color of three-color Conus / Convex / Plaque series. (4) CH-2 Control output to connect the +Control (P) and GND Control (-) wires of single-color Equator / Conus / Convex / Plaque series. The control output to connect the +Control (P) and GND Control (-) wires of GREEN color of three- color Conus / Convex / Plaque series. (5) CH-3 Control output to connect the +Control (P) and GND Control (-) wires of single-color Equator / Conus / Convex / Plaque series. The control output to connect the +Control (P) and GND Control (-) wires of BLUE color of three-color Conus / Convex / Plaque series. (6) SW1 DIP-switch to select single or three-color models and to adjust the PWM frequency of dimming for different series of underwater LED lights. (7) SW2 DIP-switch to adjust minimal dimmer value.
