GAVR-8A AVR Generator Automatic Voltage Regulator Module Universal brushless ac Diesel Alternator electric Controller stabilizerPower generator Voltage regulator 220vA generator in the boot, the remanence and a very weak voltage, this voltage back to the excitation coil of the generator and produce a stronger magnetic field, a high voltage so slowly voltage has grown. The output voltage is higher than the set voltage excitation board will control the output of the low excitation current becomes small, on the other hand, the output voltage does not control or control of very small angle, the voltage will rise.ParameterVoltage building:When the remanence is greater than 4V/25Hz automatic pressureInput power:AC 160~260V 50Hz/60HzMaximum output:8A 90V DC 10 seconds (when the input 207V AC)Adjustment rate:better than 1%Frequency Compensation:The built-in engine RPM declined when the output frequency of the voltage drop protection circuit
