Product Description

The DS3820PS5D1A is a power supply from GE.  This is a housing built with several DS3800 (or above) boards, that is designed to fit within a Mark IV gas/steam turbine series.  The MKIV was GE’s third commercially available Speedtronic system, and the first built with distributed control functions built across multiple microcomputer-run platforms.  The MKIV substantially improved reliability and decreased the turbine outage as compared to the earlier GE Speedtronic systems.

The DS3820PS5D1A is built into a heavy-duty rectangular housing designed with multiple openings for heat dissipation and air circulation. The DS3820PS5D1A has a second outer housing attached to the first; this side panel is built in a narrow “L” shape,” and connects to the side of the larger housing, but does not sit against directly against it, leaving a small gap between the two housings to allow for air flow.  The PCB that populates this smaller housing is also spaced off the floor of it. It is protected on its far end by the short end of the housing’s “L,” and is protected from above by a plexiglass shield that has been connected by four screw connections. The board has multiple Augat connectors, PCB mating connectors, and headers. It is also populated with several TP test points, an oscillating chip, and one amber LED.  

The end panel of the primary housing is held on with screws.  This allows technicians to remove this panel to gain access to the inside of the DS3820PS5D1A and the boards that are housed there.  Several cables connect from the exterior board to this panel. At least three connect to round cable screw connectors, but others connect to headers with a various number of pins.  Cables are held together using nylon cable ties.

Tech support for the DS3820PS5D1A was provided by GE.
