Feature: 1. Voltage Buildup: The generator automatic voltage regulator is internally specified to automatically build up voltage from residual generator voltage as low as 10 Vac. 2. Working Principle: System stability is the generator's ability to respond to load transients. Reduced stability allows the generator to be less sluggish and respond to transients faster. 3. Built in Fuse: The automatic voltage regulator has a built in high fusing power fuse to keep the working process and the user safe. 4. Stable and Reliable: The automatic generator voltage regulator is stable and reliable, with high accuracy and longer service life. 5. Flame Retardant and Heat Resistant PC Material: The generator automatic voltage regulator is made of flame retardant and heat resistant PC material, which is very rugged and durable. Specification: Item Type: Generator Automatic Voltage Regulator Material: PC Flame Heat Resistant Material Induction And Power Input: 190-240 Vac Load: 500 Volt Amps Output Power Continuous: 73 VDC at 3.5 ADC (255w) Output Power Forced (240 Vac Input Power): 105 Vdc at 5Adc (525w) Regulation Accuracy: 1.0% Remote Voltage Regulation Range: ±10% with 2000 Ohm Rheosta ±5% with 1000 Ohm Rheosta Frequency Compensation: Adjusting Roll Off Frequency: 54-61 Hz For 60 Hz 45-51 Hz For 50 Hz Operating Temperature: -40°C - + 60°C Storage Temperature: -65°C - + 85°C Power Consumption: 8 Watts Maximum Voltage Buildup: Internally Specified To Automatically Build Voltage From Residual Generator Voltage As Low As 10 Vac.
