Automatic Voltage Regulator (EY AVR)

The EY AVR is a voltage regulation device which is based on multi-tap transformers, where switching between taps is based on SCR technology to provide rapid response and close control of the output voltage even when the input voltage experiences large variations.

As independent regulation is achieved on each phase it is necessary to have a neutral connection. Various models are units are available to supply 1 phase, 2 phase loads from 2kVA to 75kVA, 120V AC to 240V AC (277V or 347V as a special order option) or 3 phase loads from 10kVA to 4MVA, 208V to 480V AC (600V as a special order option)
