About the DS3820PSLB1C1A

DS3820PSLB1C1A  Power Supply Module for GE Mark IV system 

The DS3820PSLB1C1A is a General Electric power supply module that is typically used in conjunction with a Speedtronic Mark IV system. The Mark IV was the first of the Speedtronic gas and steam turbine control frames to offer TMR architecture. This triple modular redundant construction that is built with multiple backups on critical controls and protection parameters significantly reduced downtime and increased reliability.   The DS3820PSLB1C1A is an obsolete unit that is no longer manufactured by GE but can be purchased from AX Control as a reconditioned and thoroughly tested unit.  Our sales representatives can provide you with a quote on all our current stock.  

The DS3820PSLB1C1A converts AC power into a DC current that is usable by the Mark IV’s internal components.   The DS3820PSLB1C1A power supply can also provide downline protection via its fuses and voltage regulating parts (such as MOVs.)  

The DS3820PSLB1C1A is constructed with an external housing that is open on multiple sides for air flow and to allow access to internal components.  The bottom of the housing has ninety-degree flanges that add additional stability to the unit, as well as providing locations for connection points for mounting.  One side of the housing has a built-in heat sink.  Board components are mounted internally and externally to this housing and are linked together using surface wiring.  Internal board components include connectors, inductor coils, high-voltage electrolytic surface-mounted capacitors, potentiometers, fuses, MOVs, and relays.
