DSEA108

Digital Automatic Voltage Regulator (AVR) with CAN Communications
The DSEA108 CAN J1939 Digital Automatic Voltage Regulator (AVR)  provides an outstanding range of 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. The onboard CAN port allows J1939 integration with third party equipment.

Please Note: The DSE815 interface is required for programming.
