I/O modules

Key Technical Specifications

This GE IS200EPSMG1A IS200EPSMG1AED module accepts 125V DC nominal input voltage. It delivers 10A total output current across five regulated DC rails. The unit measures 28 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 IS200EPSMG1A IS200EPSMG1AED includes five isolated output channels for exciter system distribution. Additionally, it features one input fuse holder for overcurrent protection. A single 8-pin terminal block connects the main DC input. The module contains 1 DC-DC converter, 5 rectifiers, 8 voltage regulators, 12 capacitors, and 24 resistors.

GE IS200EPSMG1A IS200EPSMG1AED 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 module keeps exciter controls operational through short battery sags.

Design and Integration

Both the GE IS200EPSMG1A and IS200EPSMG1AED versions share identical power topology. This module uses four-layer PCB construction with heavy copper for high current paths. Consequently, the GE IS200EPSMG1A IS200EPSMG1AED operates reliably from -20°C to +55°C ambient temperature.

For installation, you need M4 screws for the six mounting holes. The module 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 exciter power supply module converts 125V station battery power into multiple logic voltages. It feeds regulator boards, I/O modules, and communication interfaces in an exciter rack. The GE IS200EPSMG1A IS200EPSMG1AED also provides power good signals for each output rail. Therefore, it serves as the primary power source for GE exciter control systems.
