AC voltage regulator DSEA109

three-phasedigitalautomatic

The DSEA109 Digital Automatic Voltage Regulator (AVR) with CAN is designed to regulate the output voltage of an AC alternator. The DSEA109 is supplied by either a 3 phase PMG, single phase PMG, stator auxiliary winding or a shunt system taking power from the output windings. The DSEA109 eliminates the complexities involved with analogue AVR designs. Analogue AVR designs can be over sensitive to changes in temperature which affects stability whereas the DSEA109 AVR maintains a smooth, stable regulated AC output voltage, regardless of the electrical load connected.The DSEA109 also features 3-phase sensing for better regulation.
