Feature:1. The excitation generator voltage regulator uses the exciter selfPMG as the excitation power supply, and the voltage is stable.2. Good load, with DROOP parallel functions, the automatic voltage regulator is suitable for P0/ P1 series generators.3. This voltage regulator board is the AVR for the Stanford generator , this AVR voltage adjustment rate is < 1.0%.4. The singlephase 120/240 VAC detection voltage is selected by using the crossover copper.5. Can be used in parallel units, and set with crossover copper plates to match different power generators. Ideal for selfexcited brushless generators.6. Low frequency protection inflection point adjustment, low frequency protection voltage/ frequency slope adjustment, single phase voltage detection.Specification:Item Type: Generator Voltage RegulatorModel: AS480Detection and Power Input: 120 (95-132) / 240 (190-264) V ACSingle-phase, two-wire, selected by jumper copper.
