GAVR-15C Diesel Generator AVR Voltage Regulator Spare Part

GAVR-15C is an automatic voltage regulator module used in diesel generator sets and power generation equipment to help control excitation and stabilize generator output voltage during load changes. Based on the available product information, it is a single phase AVR with 220V sensing and power input, 50-60Hz nominal frequency, minimum 15 ohm field resistance, and stated voltage regulation performance for generator maintenance applications. The module connects with the main stator windings and exciter field windings to provide closed loop voltage control, using semiconductor power circuitry to support positive voltage build-up from residual magnetism. This product is most suitable for generator repair workshops, industrial backup power service teams, genset distributors, rental fleet maintenance, and aftermarket spare parts procurement. Buyers can use it as a replacement AVR when selecting compatible parts for diesel gensets that match the required sensing input, field output, terminal layout, and installation form. Its compact open-board structure with a protective base, terminal block, adjustment components, and wiring interface supports practical installation inside generator control or alternator service areas. For B2B procurement, the GAVR-15C supports stable sourcing, maintenance inventory planning, replacement selection, and OEM/ODM spare parts cooperation for power generation service networks.
