ADVR-2300M

3.5Amp Hybrid Analog/Digital AVR for Shunt, PMG/Aux. Winding Genset

ADVR-2300M is a hybrid Analog/Digital AVR which is compatible with Marathon DVR2000 Series. This voltage regulator can be used on single/three phase sensing and Shunt/PMG/Aux.Winding. It has PF (power factor) correction inputs and the facility for droop CT connection.
* It can be used with KUTAI IVT Generator Excitation Booster to increase motor starting capacity.
* If not for use with the IVT Generator Excitation Booster, the ADVR-2100M can be used instead,and purchased at a big discount.
