GE DS200UPLAG1A DS200UPLAG1APR2 Power Supply Board

Key Technical Specifications

This GE DS200UPLAG1A DS200UPLAG1APR2 board accepts 125V DC nominal input voltage. It delivers 10A total output current across five regulated rails. The unit measures 30 cm in length, 20 cm in width, and 6 cm in height. Its total weight reaches 1.3 kg without any packaging materials.

The GE DS200UPLAG1A DS200UPLAG1APR2 includes five isolated DC outputs for system power distribution. Additionally, it features one input fuse holder for overcurrent protection. A single 8-pin terminal block connects the main DC input. The board contains 1 transformer, 5 rectifiers, 8 voltage regulators, 12 capacitors, and 24 resistors.

Energy Storage	2200 µF at 200V

GE DS200UPLAG1A DS200UPLAG1APR2 stores energy using two large electrolytic capacitors. Together, they provide 2200 µF at 200V rating for input hold-up. This energy storage maintains all outputs during 50 millisecond input interruptions. Therefore, the board keeps control systems operational through short power sags.

Design and Integration

Both the GE DS200UPLAG1A and GE DS200UPLAG1APR2 versions share identical power topology. These boards use four-layer PCB construction with heavy copper for high current paths. Consequently, the GE DS200UPLAG1A DS200UPLAG1APR2 operates reliably from -20°C to +55°C ambient temperature.

For installation, you need M4 screws for the six mounting holes. The board draws 8A typical input current at full load. Each output includes short-circuit and overcurrent protection. We recommend using 12 AWG wire for the DC input connection.

Practical Application

This power supply board converts 125V station battery power into multiple logic voltages. It feeds processor boards, I/O modules, and communication interfaces in a control rack. The GE DS200UPLAG1A DS200UPLAG1APR2 also provides power good signals for each output rail. Therefore, it serves as the primary power source for GE drive and turbine control systems.
