IS200JPDEG1A | GE Mark VI DC Battery Power Distribution Board

Product Overview

The GE IS200JPDEG1A is a DC Battery Power Distribution Board for the Mark VI Speedtronic turbine control system. It distributes a single DC battery source into multiple protected loads, accepting 24 VDC or 48 VDC input (with 125 VDC compatibility in some configurations) and providing organized power routing through 12 fuses and 6 toggle switches. The board features 6 LED status indicators for power monitoring and is installed vertically in the PDM (Power Distribution Module) cabinet. It requires a PPDA I/O pack for integration into the Mark VI control system.

Installation Guide

1. Mount the IS200JPDEG1A vertically in the PDM cabinet, ensuring adequate airflow and access to toggle switches.
2. Connect the primary and secondary DC battery sources (24 VDC or 48 VDC) to the input terminals.
3. Wire distributed loads to the JD1–JD6 output connectors through the protected fuse circuits.
4. Connect the PPDA I/O pack for system monitoring and feedback integration.
5. Verify all 12 fuses are properly rated for downstream load currents.
6. Energize the board and confirm all 6 LEDs indicate correct power status per GEH-6721L.

FAQ

• Q: What is the primary function of IS200JPDEG1A?
  A: It is a DC battery power distribution board that splits a single DC source (battery) into multiple fused, switch-protected outputs for Mark VI system components.
• Q: What voltage inputs does it support?
  A: Standard configurations support 24 VDC or 48 VDC. Some system configurations may support 125 VDC; verify against the specific Mark VI PDM design.
• Q: Is the DC bus grounded or floating?
  A: The DC bus is floating (ungrounded), which is standard for Mark VI battery distribution to reduce ground fault risks.
• Q: What is the PPDA I/O pack used for?
  A: The PPDA I/O pack is required to integrate the JPDEG1A into the Mark VI control system, providing monitoring and diagnostic feedback to the controller.
• Q: How many loads can be connected?
  A: The board provides 6 switched output circuits (JD1–JD6) with 12 fuses for overcurrent protection, supporting multiple distributed loads.
• Q: Does installation location within the panel matter?
  A: As long as the board is mounted vertically with adequate clearance for airflow and maintenance access, specific cabinet location is not critical.
