Product Description

DS2020EXPSG3 GE Mark V Exciter Power Supply Module (EX 2000) 

The DS2020EXPSG3 is a power supply module fabricated by GE for use within their Speedtronic Mark V series.  While GE no longer manufactures these boards, they are available through AX Control as reconditioned and fully tested modules. 

The DS2020EXPSG3 is an Exciter Power Supply Module for the EX2000 brushless generator excitation system.   

The DS2020EXPSG3 has three primary sections.  These include a large metal base with an attached circuit board, a second metal tier with an attached circuit board, and a plexiglass shield.  The circuit boards on each tier communicate with each other via surface mounted wired connections.  The plexiglass shield screw mounts to the surface of the second tier and is removable.  It carries a large warning label stating the dangers of electrical shock or burns if the unit is mishandled. 

The bottom metal carrier of the DS2020EXPSG3 is built with two top hat flanges that have each been drilled twice to allow the unit to be easily mounted in place.  The metal carrier has a two-by-two terminal strip mounted to one corner.  The circuit board component on this level is a DS200GDPA board that is populated with heat sinks, transformers, fuse components, stab-on connectors, transistors, high-voltage capacitors, and wire-wound resistors.  This board also has multiple LED indicators.  

The top circuit board is marked DS200EXPS.  It mounts to the metal carrier via multiple standoffs inserted into factory-made drill holes.  The board is populated by terminal strips, heat sinks, metal oxide varistors, and inductor coils, along with various resistors and capacitors.
