DS200EXPSG1A GE MarkV, Bulk Power Supply Board

Description:

The DS200EXPSG1A a product of General Electric's design and manufacturing prowess, functions as a Bulk Power Supply Board within the framework of the MarkV Series, tailored for application in Drive Systems. This sophisticated board harnesses signals from the Expansion Signal Processing System (EXPS) to meticulously gauge both AC and DC input power levels. Activation via the station battery not only energizes the system but also initiates a current-limiting mechanism for added protection.

Identification of this printed wiring board, emphasizing its role as an EXPS component, is anchored by the base number DS2OOEXPS. Revision stages of the board are articulated through a unique combination where alphabetic characters 'I' and 'u' intermingle with numerical values. An 'r' prefix in these revision indicators signifies modifications that break compatibility with earlier versions, heralding a fresh catalog entry. Conversely, revisions marked by 'II' ensure compatibility with their predecessors. To further delineate variations among boards, a 'G#' designator is employed, specifying distinct board models within the series.

FEATURES:
The board's components are shielded from over-voltage and erratic voltage conditions by three fuses, which safeguard against excessive circuit voltage. If voltage exceeds limits, the fuse's element melts, isolating the circuit, cutting power, and protecting all components.

Should a fuse blow, it's imperative to diagnose the root cause of the overvoltage issue before replacement. For those unfamiliar with the drive's electrical supply, seek guidance from an engineer or qualified personnel. Fuse specifications can be found in the accompanying documentation.

Only replace fuses with identical ratings to prevent component damage due to improper voltage exposure. Once the over-voltage issue is resolved, disconnect power before proceeding.

BOARD REPLACEMENT GUIDE:
1. Begin by fully removing the bulk power supply and ensuring zero potential across all power supply connections.
2. Carefully detach the following connectors to remove the power supply assembly:
   - Disconnect the LFTB, 1TB-8TB, DCTB, VM2A, and VM2B connectors as necessary.
   - Detach the black and white wires from the CPS PTB1 and PTB2 terminal boards.
   - Unplug the ACPL.
3. Loosen the four mounting screws to extract the power supply assembly from the cabinet, leaving the ACPL intact.
4. At a workstation, unscrew the four fasteners holding the plastic cover in place and disconnect the DCPL, 3GDPL, and 4GDPL connectors from the EXPS board.
5. Swap the old EXPS board for the new one, aligning the JPL on the replacement board with its position on the original.
6. Reattach all connectors removed in step 5.
7. Secure the plastic cover back onto the assembly and reinstall it into the cabinet. Reconnect the previously disconnected connectors from step 3.

Frequently Asked Questions:
