GE MARK V DS200EXPSG1ACB BULK POWER SUPPLY BOARD

Product Description:

The GE DS200EXPSG1ACB is a Bulk Power Supply Board part of GE’s Mark V Turbine Control System series—one of the final Mark iterations to integrate GE’s patented Speedtronic technology. It is a revised version of the original DS200EXPSG1, featuring two functional updates and one artwork revision, designed to deliver bulk power for Mark V turbine control systems.

Physically, it includes key hardware: a reset button, 3 fuses, a green status LED, 3 9-pin connectors, multiple capacitors, and test points for circuit troubleshooting. A single Berg-type jumper (JP1) is present but strictly for manufacturing testing—no user adjustment is permitted. Its core logic is managed by a 5C060 programmable logic device. Installation requires power removal from the board, verifying zero power at all connections, and following manual-guided connector unplugging—critical due to potential damaging surface voltages.

Key Features:

Revised Performance: Builds on the original DS200EXPSG1 with two functional and one artwork revision, enhancing power supply stability or compatibility for Mark V setups.

Clear Status & Diagnostics: A green LED indicates normal operation, while test points enable targeted troubleshooting of faults—simplifying maintenance and reducing downtime.

Safety-Focused Design: Requires strict power-off installation due to hazardous surface voltages and includes 3 fuses for circuit protection, aligning with industrial safety standards.

Non-Configurable Jumper: JP1 is restricted to manufacturing testing, preventing unintended user adjustments that could disrupt power supply functionality.

Programmable Logic Control: Relies on a 5C060 programmable logic device for system logic management, ensuring precise, consistent power supply operation tailored to Mark V requirements.
