Product Description

The  DS3820PSWA is a power supply board for the Mark IV system.  The Mark IV was the third commercially released version of GE’s Speedtronic gas and steam turbine management system (preceded by the MKI and the MKII.)  The MKIV is built upon interconnected microprocessors which independently monitor the turbine for such issues as vibration, high pressure, fire, loss of flame, over speed, and over temperature.  The MKIV is also designed to automate such procedures as startup, GT protection, control sequencing, and shutdown.

The DS3820PSWA is a power supply board.  It is a relatively small board, but it is vertically heavy due to its (C1) component, which is a large 300VDC capacitor attached to the board using the help of a clamp with multiple screws.  One other capacitor also populates the board; this is a polyester vinyl m/e 200V +/- 10% capacitor. The board has three resistors that are all made of different materials. R1 is a carbon composite resistor.  R2 is a wire wound resistor marked 8431 TRW 10W 3K 5%. R3 is a ceramic covered metal film resistor.

The DS3820PSWA has one transformer located on the board.  The transformer is marked 138A1012P1 on its metal casing. The front of the transformer is marked 23V17 “isolation transformer” PRI. 117V 50/60 Hz.  

Most wiring on the DS3820PSWA terminates at the terminal block located in the lower corner of the board.  This terminal block is screw mounted to the surface of the board. It has six double screw terminals. All wires leading to these terminals are black, but the ends of the first three connections are red, white and blue.  

The DS3820PSWA is designed with top hat flanges projecting from either short end of the board.  Each of these has two openings for mounting screws.

All technical support for the DS3820PSWA originally came from GE.
