Power Conversion and Filtering Features

The GE DS200SDCIG1A DS200SDCIG1AHB DC Power Supply and Instrumentation Board converts high DC voltage into four regulated outputs. Each output has overcurrent and overvoltage protection circuits. The DS200SDCIG1AHB variant adds a common mode choke for better noise rejection. Furthermore, this board uses switching regulators for high efficiency above 85%. As a result, it generates less heat than linear power designs.

Installation and Connection Steps

Mount this GE DS200SDCIG1A DS200SDCIG1AHB DC Power Supply and Instrumentation Board in any standard Mark V rack slot. First, connect the input DC power to TB1 terminals 1 and 2. After that, attach your load devices to the output terminals on TB2. Then, secure the board using four M4 mounting screws. Finally, verify each output voltage before connecting sensitive loads.

Energy Discharge and Safety Notice

This GE DS200SDCIG1A DS200SDCIG1AHB DC Power Supply and Instrumentation Board stores significant energy in its four capacitors. Therefore, you must wait at least three minutes after power removal. The capacitors discharge through internal bleeder resistors during this time. Never short the output terminals to discharge the board faster.

Status Indication and Diagnostics

Four green LEDs show the presence of each output voltage on this board. A red fault LED illuminates when any output falls out of range. These indicators help technicians diagnose problems without any test equipment.
