GAVR-15B AVR Automatic Voltage Regulator Brushless Generator Spare Parts This product can stabilize the output voltage of the brushless generator by adjusting the excitation current of the generator, and can establish the voltage slowly. It is suitable for generator sets above 120KW.   Features:  Automatic Voltage Regulator forms part of the excitation system for a brushless generator. The AVR realizes the automatic adjustment of the generator output voltage by controlling the excitation current of the generator. The voltage regulator uses flame retardant and high temperature resistant components to guarantee safety use. Built-in low frequency protection functions. Stable performance, long service life. Specification: Model: GAVR-15B Input power: R, N = 170V~265VAC 50/60Hz Detection power supply: R, L = 170V~265VAC; R, H=380V~440VAC 50/60Hz Maximum output: 15A 90VDC (at 240VAC input power) Voltage regulation rate: ≤0.5% Generator magnetic field resistance: Min. 9Ω External potentiometer: 1kΩ, 1/2W ± 8% Low frequency protection: If 60Hz generator is lower than 55Hz or 50Hz generator is lower than 45Hz, the regulator will be turned off immediately Operating temperature: -40~60℃   Package list: 1 x Automatic Voltage Regulator
