General Electric DS200VPBLG1AEE Mark VI Power Supply Board

General Electric DS200VPBLG1AEE Mark VI Power Supply Board

Configured for power distribution and regulation in GE Mark VI Series systems, the General Electric DS200VPBLG1AEE (DS200VPBL Power Supply Board) provides direct physical/electrical execution. This printed circuit board (PCB) converts raw input from the system AC/DC bus into isolated, regulated internal DC voltage rails—including +5 VDC, +15 VDC, and -15 VDC—to power connected control logic and peripheral expansion cards. Onboard interface sections J2 and J3 directly manage power distribution routing to attached DSPC boards, Gate Distribution and Status Boards, I/O extenders, and exciter modules directly through the card cage backplane.

Hardware Specifications

Deterministic Backplane Power Routing & Firmware Synchronization

The General Electric DS200VPBLG1AEE utilizes low-impedance trace matrices and embedded regulation stages to deliver stable power rails across the high-speed backplane bus, maintaining firmware flash compatibility across connected digital processing boards. The board provides stable current distribution across expanded card configurations via the J2 section—which accommodates a DSPC board, up to three Gate Distribution and Status Boards, an I/O extender, and an exciter module—while suppressing electrical noise and voltage drop during high-load switching events.

Frequently Asked Questions

Q: What functions do the J2 and J3 connectors serve on the DS200VPBLG1AEE board?

A: The J2 connector interface supplies power and control routing to attached expansion modules including a DSPC board, up to three Gate Distribution and Status Boards, an I/O extender, and an exciter board with two spare expansion slots. The J3 connector interface routes external connections that cannot fit on the front panel board edge due to mechanical space constraints.

Q: Is hot-swapping permitted for the DS200VPBLG1AEE during live system operation?

A: No. Removing or inserting the power supply board while the main bus is energized causes transient current spikes and arc flash hazards that damage sensitive onboard regulators and microprocessors. Disconnect all primary power sources before extraction or replacement.

Q: Why must the AEE revision suffix match when replacing an existing DS200VPBL board?

A: Revision suffixes indicate hardware artwork iterations, component trace adjustments, and power regulation tolerances. Installing a board with mismatched suffix revisions can result in bus signal distortion or physical pin incompatibility with secondary daughter cards.

Field Installation Guidelines

1. De-energize the host drive chassis and verify zero-voltage conditions on both the primary AC/DC bus lines and internal 24 VDC control power rails using a calibrated multimeter.
2. Fasten an ESD grounding wrist strap to your wrist and attach the clamp to a bare metal earth-grounded chassis point prior to handling the board.
3. Align the card edges with the plastic guide rails of the designated rack slot inside the GE Mark VI cabinet, then slide the card in until the rear edge pin connectors align with the backplane.
4. Press firmly on the card ejector handles to seat the multi-pin connectors fully into the backplane, J2, and J3 ribbon interfaces.
5. Tighten all front-panel retaining screws to 0.8 Nm (7 in-lbs) to ensure electrical grounding integrity and mechanical retention against vibration.
