Shipment from Manila Philippines AS440 AVR brushless generator voltage regulator AVR Stanford automatic excitation regulator unit (directly issued by the manufacturer)

Voltage establishment: Automatically builds voltage when residual magnetism exceeds 4V25Hz Input power supply: AC 190-260V 50/60Hz Output: Voltage 90V DC (when inputting AC 207V) Current 4A (continuous) 6A10S (instantaneous) Frequency compensation: a built-in frequency protection circuit that reduces the output voltage when the engine speed decreases Adjustment rate: better than 1% Voltage regulation: less than+/-1% (4% for motor control), the voltage changes steadily during startup. Prevent voltage loss from reading. 120 or 240 V AC sensor, selectable by jumper Frequency reduction protection. Downward LED frequency indicator light
