Power Conversion and Regulation Features

The GE DS200EXPSG1A DS200EXPSG1ACB Power Supply Board uses a flyback converter topology. This design provides excellent line regulation across the entire input range. Each output has independent overcurrent protection with automatic recovery. Furthermore, the board includes overvoltage protection on all output rails. Consequently, downstream cards receive clean, stable power continuously.

Installation and Connection Steps

Mount this GE DS200EXPSG1A DS200EXPSG1ACB Power Supply Board in any EX2000 cabinet slot. First, connect the AC or DC input to the TB1 terminals. After that, attach your load devices to the output terminals on TB2. Then, secure the board using four M4 mounting screws at the corners. Finally, verify each output voltage before connecting sensitive field circuits.

Energy Discharge and Safety Notice

This GE DS200EXPSG1A DS200EXPSG1ACB Power Supply Board stores significant energy in its capacitors. Therefore, you must wait at least three minutes after power removal. The four bulk capacitors discharge through internal bleeder resistors. Never short the output terminals to discharge the board faster.

Status Indication and Diagnostics

Four green LEDs show the presence of each output voltage clearly. A yellow LED indicates the board is in normal operating mode. A red fault LED illuminates when any output falls below 90% of nominal. These indicators help technicians diagnose power issues without any test equipment.
