Description
The GE DS3820PSCB is a power supply assembly for the General Electric Speedtronic Mark IV turbine control system. It uses multiple DS3800-series circuit boards housed in a metal frame and provides DC power rails identified as +5 V and +/-15 VDC in product-specific listings. The assembly includes an external DS3800XTFP connector board, a fuse, a circuit breaker, and an internal enable/disable switch.
Functional Description
The DS3820PSCB supplies the DC voltages required by compatible Mark IV control electronics. Its multiple-board construction combines power conversion circuitry and associated components within one assembly. The listed output rails are +5 VDC, +15 VDC, and -15 VDC; these rails serve different circuit requirements and should be verified against the installed system's wiring and documentation before replacement.
The Mark IV platform uses distributed control functions to manage gas and steam turbine operation, including sequencing and protective logic. The DS3820PSCB is a power supply component within that platform, not the turbine's complete control or protection system.
Hardware and Connections
The assembly consists of a rectangular metal housing with mounting holes, slotted flanges, and openings for access and air circulation. Multiple printed circuit boards are installed inside the frame, with an additional DS3800XTFP board fastened to the exterior.
The externally mounted DS3800XTFP board has one 6-pin male header and eight 12-pin female connectors. The housing also carries a 4-pin female connector, a fuse, and a circuit breaker. An internal PCB-mounted toggle switch corresponds to the enable/disable marking on the frame. Confirm connector positions and wiring against the installed assembly before disconnecting or replacing it.
