ADVR-2100M

Automatic Voltage Regulator (AVR) substitutes for Marathon DVR2000 Series

ADVR-2100M is a hybrid Analog/Digital AVR that replaces Marathon DVR2000 Series. It can be either single or three phase sensing and PMG. It has Over Excitation Protection and also the capabilities for DROOP Parrelleling.
* It cannot be used with KUTAI IVT Generator Excitation Booster. If the AVR is intended to be used with IVT-1260 or IVT-2460, ADVR-2300M is the recommended model.
