The AVC63-4A Basler Voltage Regulators are designed for use on 50/60 Hz brushless generators. The regulator includes frequency compensation, overexcitation shutdown, a solid-state build-up circuit, and EMI filtering.

The AVR AVC63-4A model voltage regulator maintains generator line voltage on brushless generators from 5 kW to over 100kW in size. The voltage regulator senses generator average voltage to maintain a precise regulation band within ± 1percent. This is accomplished by converting a 120 VAC single phase power input to a controlled DC signal to the generator’s exciter field. The solid-state voltage build-up circuit will enable automatic generator line voltage build-up with a voltage input to the regulator of at least 6 VAC. Customer accessible stability, underfrequency and range adjusts enable fine tuning of the voltage regulator to the generator in use.
