PRODUCT INFORMATION
Product Overview
The General Electric DS200EXPSG1ACB is a Mark V series bulk power supply board. It operates in Speedtronic Mark V control systems for industrial turbine management. This printed circuit board delivers regulated direct current power across turbine control rack assemblies. A dedicated 5C060 programmable logic device manages complete board-level system logic. The unit features one reset button, three fuses, and three 9-pin connectors.
The DS200EXPSG1ACB incorporates revisions over the original DS200EXPSG1 hardware design. These updates include two functional modifications and one artwork revision. Onboard diagnostics feature a green status LED to confirm active operation. Surface test points allow technicians to inspect and verify individual internal circuit stages. The assembly uses standard board coating without special hardware modifications.

PRODUCT FAQ
Frequently Asked Questions
What does an unlit status LED indicate on the DS200EXPSG1ACB?
An unlit green LED indicates that the board failed startup diagnostics or lost operational power. Technicians should verify input voltages and inspect onboard test points to isolate circuit faults.
Can maintenance technicians reconfigure the onboard JP1 jumper?
No, technicians should not move this jumper. The JP1 Berg jumper is exclusively reserved for factory manufacturing tests.
What manual governs maintenance on the General Electric DS200EXPSG1ACB board?
Official publication GEI-100168 provides formal installation guidelines and circuit test point definitions.
