Power Conversion and Regulation Features

The GE DS200DCFBG1A DS200DCFBG1AAA EX2000 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 achieves 87% typical efficiency at full load. As a result, it requires only passive cooling for reliable operation.

Installation and Connection Steps

Mount this GE DS200DCFBG1A DS200DCFBG1AAA EX2000 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 screws at the corners. Finally, verify each output voltage before connecting sensitive field circuits.

Energy Discharge and Safety Notice

This GE DS200DCFBG1A DS200DCFBG1AAA EX2000 Power Supply Board stores significant energy in its capacitors. Therefore, you must wait at least two minutes after power removal. The three 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.
