2.2 PMG / AUXILIARY WINDING / SHUNT SUPPLY
NOTE: The DSEA109 AVR is suitable for alternators with PMG, Auxiliary Winding or Shunt
connections.
CAUTION!:
The source powering the AVR must have inrush protection if it’s internal
impedance is less than 3
Ω
. This is typically the case when using a bench power supply.
Failure to do so may result in the power source becoming damaged.
