GAVR 20A Brushless Generator AVR 4-Potentiometer Module

Product Overview: The GAVR 20A is a brushless generator automatic voltage regulator designed for diesel generator sets, standby power systems and industrial power generation equipment. It is used to regulate generator excitation and support stable output voltage during load changes, making it an important electrical control component for genset maintenance and aftermarket service. This AVR features a compact heat-sink housing, screw terminal wiring interface and four adjustment potentiometers for field setup. Based on the provided configuration, it supports 190-240VAC sensing/power input, 50/60Hz operation, max 95VDC output at 240VAC input and continuous 20A output current. Functional features include voltage regulation, soft start voltage ramping, sensing voltage loss protection, jumper-selectable 120V or 240V sensing, under-frequency roll-off protection and an under-frequency LED indicator. It is commonly procured as a compatible replacement for Vision Series GAVR20A applications where buyers need reliable generator spare parts for repair, maintenance or inventory support. For B2B distributors, genset service companies and power equipment suppliers, this AVR provides a practical sourcing option for generator maintenance networks, industrial backup power projects and OEM/ODM spare parts cooperation.
