Feature: This product can be used to adjust the generator voltage. Overload voltage protection for safer use. Low speed protection for better protection of the generator. The voltage range is adjustable and the use is more flexible. High voltage stability, safe and reliable. The voltage frequency is 50HZ/60HZ adjustable. The AS480 excitation generator voltage regulator uses the exciter self-PMG as the excitation power supply, and the voltage is stable. Good load, with DROOP parallel functions.AS480 is suitable for P0/ P1 series generators. AS480 is the AVR for the Stanford generator , this AVR voltage adjustment rate is <± 1.0%. The single-phase 120/240 VAC detection voltage is selected by using the crossover copper. Select 50/ 60Hz by crossover copper. Loss detection voltage protection circuit. Low frequency protection (UFRO) and slow voltage establishment function. LED indicating low frequency state. AS480 can be used in parallel units. It can be set with crossover copper plates to match different power generators. It is suitable for self-excited brushless generators. Pressure regulation accuracy is <± 1% Low frequency protection inflection point adjustment, low frequency protection voltage/ frequency slope adjustment, DROOP parallel, single phase voltage detection.
