GE IS200JPDVG1A IS200JPDVG1AAA | Power Distribution Board

Core Function and System Role

The GE IS200JPDVG1A distributes high-current DC power for Mark VI systems. Specifically, this board receives 125 Vdc from the main battery bank. Moreover, it routes power to large contactors and motor starters. The IS200JPDVG1AAA variant includes individual LED indicators for each output channel.

Technical Specifications Overview

This power distribution board features one main input and eight fused outputs. Each output channel provides 15 amperes of continuous current. Furthermore, the board includes surge suppression for inductive load protection.

Connector Layout and Component Count

The board uses two terminal blocks for main power input. For instance, terminals TB1-1 and TB1-2 accept positive 125 Vdc. Meanwhile, terminals TB2-1 and TB2-2 provide the return path. Four output terminal blocks host the eight fused channels. The IS200JPDVG1AAA adds eight green LEDs for visual status indication.

Energy Storage and Power Stability

This distribution board includes large capacitance for surge absorption. Specifically, eight 1500 µF capacitors filter incoming DC power. Therefore, the board supplies stable voltage during high-current motor starting. Additionally, a red LED on the main input confirms proper supply voltage. A blown fuse triggers an individual LED off-state for easy troubleshooting.

Diagnostic Features and Fault Isolation

The board isolates each output channel with an independent fuse. Consequently, a single short circuit does not affect other channels. Moreover, the GE IS200JPDVG1A IS200JPDVG1AAA includes a blown fuse detection circuit. This feature reports any open fuse back to the main controller. An onboard status register monitors all eight channels simultaneously.

Maintenance and Fuse Replacement

You can replace any blown fuse without removing the distribution board. Thus, mean time to repair remains under five minutes. The board accepts standard 10 x 38 mm fuses for easy sourcing. Therefore, you simply swap the faulty fuse and restore normal operation.

Industrial Applications

This power distribution board works inside GE Mark VI control cabinets. For reliable GE high-current DC distribution, the IS200JPDVG1A and IS200JPDVG1AAA deliver exceptional performance. They provide safe power routing for steam and gas turbine auxiliary systems.
