Feature: 1. Voltage Regulator: AVR adopts high efficiency semiconductor. Within the input and output, it can achieve high miniaturization when applied to 30 and 10 AC brushless generators. 2. Stable in Working: The AVR provides DC excitation to the excitation field of the brushless generator to maintain the terminal voltage within a close range from no load to full load. 3. Quick Recovery: The recovery time in case of sudden loading may be about 0.5 seconds to recover 98% of the rated voltage. Please note that transient performance such as voltage sags and recovery times depends primarily on the design parameters of the generator and exciter. 4. Best Performance: The best performance of the regulator can be obtained by keeping the full load excitation at about 60V DC. 5. Simple to Install: Comes with a compact size and a light weight, the automatic voltage regulator AVR can be conveniently installed in minutes.
