DSEA106MKII

Digital Automatic Voltage Regulator (AVR)

The DSEA106 MKII Digital Automatic Voltage Regulator (AVR) builds on the success of the DSEA106 product providing additional features to enhance customer applications. The product regulates the output voltage of an AC alternator and is supplied by a stator auxiliary winding or a shunt system taking power from the output windings.

The product provides higher levels of stability compared to analogue designs by maintaining a smooth, stable and regulated AC output voltage that is unaffected by the connected electrical load.

Please Note: The DSE815 interface is required for programming.
