About the DS3820PS1B1E1E

The DS3820PS1B1E1E is designed as a power supply for GE’s Speedtronic MKIV series.  Built on dedicated control theory, the Mark IV takes care of the turbine system by monitoring and automating such things as temperature, power supply, control sequencing, start-up, and shutdown.  

The  DS3820PS1B1E1E is a modification built out of DS3800 series boards with additional components added.  The DS3820PS1B1E1E has a large rectangular housing with several openings to allow for heat dissipation and/or to allow technicians access to those components placed within the interior.   This housing has tabs and drill mounts for screws, and the frame is drilled at several places to allow for the mounting of components. Flanges on the DS3820PS1B1E1E may flare inward or outward.  The top of this housing is open, but it is worth noting a PCB has been mounted outside and above the framework. Four spaces have been utilized to leave enough of a gap between the frame and the PCB to allow for air circulation.  This PCB has been mounted with all components facing inward. Components on the board include several male mating connectors that range from two pins to twelve pins. All connectors are labeled. The board is also populated with test points, light emitting diodes, potentiometers, capacitors, and resistors.  The housing has a switch and a terminal strip mounted near the PCB, on its top edge.

Inside the  DS3820PS1B1E1E there are many more components.  This includes two large capacitors fitted with collar clamps, heatsinks, a terminal strip with multiple connections, a coil inductor connected to the frame via a nylon cable tie, and two transformers.  Cables also run from components to two female 12-pin plugs mounted into the side of the housing.

Tech support for the  DS3820PS1B1E1E was provided by GE.
