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. Employing a digital circuit for voltage sensing and under frequency protection, it can effectively minimize the output voltage variations and under frequency knee point drifted affected by the changes of environment temperature.
* Compatible with KUTAI EPMG Excitation Boost Module or IVT Excitation Auxiliary Power Converter to boost for self-excited (shunt) generator during heavy transient loads.
