DESCRIPTION for AVC63-4 AVR
The AVC63-4 AVR and AVC63-4D voltage regulators maintains generator line voltage no load to full load on brushless generators from 5kW to over 100kW in size.
These voltage regulators sense generator average voltage to sustain a precise regulation band within ±1% throughout the operating temperature range. This is accomplished by converting a 240Vac single phase power input to a controlled DC output signal.
The solid-state voltage build-up circuit allows automatic generator line voltage build-up with as little as 6 Vac residual voltage applied to the regulators input power circuit.
Customer accessible adjustments for stability, underfrequency and the voltage regulation set point are provided to allow the controller to be tuned to the desired performance. The location of these adjustments are different depending on which model is selected. Both, the AVC63-4 AVR and the AVC63-4D are intended to be mounted inside the generators terminal box. For applications that require the voltage regulator adjustments to be made from outside of the terminal box, the AVC63-4D should be considered.
