Product Description


- This AVC63-4 voltage regulator is an encapsulated automatic electronic voltage regulator that controls the output of the generator by regulating the current into the exciter field. The low frequency protection 60Hz system presets the inflection point to 54-61Hz, and the 50Hz system presets the inflection point to 45-51Hz. Maximum power consumption per unit is 8W.
