Key Technical Specifications
This GE IS200WNPSH1A IS200WNPSH1ABA daughter card accepts 24V DC input voltage. It delivers 2A total output current across four regulated DC rails. The unit measures 15 cm in length, 12 cm in width, and 3 cm in height. Its total weight reaches 0.35 kg without any packaging materials.
The GE IS200WNPSH1A IS200WNPSH1ABA includes four isolated output channels for system power. Additionally, it features one 20-pin header for motherboard interface. A single 4-pin terminal block connects the main DC input. The card contains 1 DC-DC converter, 4 rectifiers, 6 voltage regulators, 8 capacitors, and 14 resistors.

GE IS200WNPSH1A IS200WNPSH1ABA stores energy using one electrolytic capacitor. This capacitor provides 220 µF at 50V rating for input hold-up. This energy storage maintains all outputs during 25 millisecond input interruptions. Therefore, the card keeps logic circuits operational through short voltage sags.
Design and Integration
Both the GE IS200WNPSH1A and IS200WNPSH1ABA versions share identical power topology. This daughter card uses four-layer PCB construction with heavy copper for high current paths. Consequently, the GE IS200WNPSH1A IS200WNPSH1ABA operates reliably from -20°C to +55°C ambient temperature.
For installation, you need M2.5 screws for the four mounting holes. The card draws 1.8A typical input current at full load. Each output includes short-circuit and overcurrent protection. We recommend using 20 AWG wire for the DC input connection.
Practical Application
This power supply daughter card converts 24V DC input power into multiple regulated voltages. It feeds processor, memory, and logic circuits on a motherboard. The GE IS200WNPSH1A IS200WNPSH1ABA also provides power good signals for each output rail. Therefore, it serves as a compact power source for GE control system daughter cards.
