GAVR-50A Automatic Voltage Regulator AVR for Generators

The GAVR-50A automatic voltage regulator is a generator electrical control component for general brushless generator sets used in standby power, industrial power generation, rental equipment, maintenance workshops, and aftermarket service networks. This AVR supports excitation voltage regulation for brushless alternators and is suitable for procurement teams seeking replacement generator spare parts for diesel genset repair and power backup system maintenance. It is designed around 220/400VAC single phase two wire sensing and power input, with 50/60 Hz jumper selectable operation, a maximum 90VDC output at 240VAC input, and provided current data of continuous 6A and intermittent 75A for 10 seconds. Key functional value includes voltage regulation, soft start voltage ramping, sensing voltage loss protection, selectable 120 or 240VAC sensing, under frequency roll off protection, and an under frequency LED indicator. Buyers should confirm alternator wiring, sensing terminal layout, installation space, existing AVR model, and generator set requirements before replacement. As a B2B sourcing item, this GAVR-50A AVR helps distributors, service companies, OEM/ODM partners, and genset maintenance providers support stable parts availability, faster repair planning, and reliable generator accessory procurement.
