Feature:1. SEALING DEVICE: The GAVR20A voltage regulator is a sealed electronic device that stabilizes the brushless generator to the output voltage by adjusting the generator excitation current2. STABLE RESPONSE: Ultra low starting voltage, possess quick response, more stable voltage, you can use with confidence3. SAFE PROTECTION: The key loop adopts industrial grade high stability component, temperature drift is less than 0.05%/. Multiple independent protection circuit design, more safe and reliable4. SUITABLE FOR GENERATORS: Low frequency protection with slow build up voltage, EMI suppression circuit, high capacity 8A fuse protection, suitable for brushless generator suitable for 220/440VAC (programmable input)5. SCRATCH RESISTANT ABS: Adopt excellent ABS material, possess impact resistance, scratch resistance, environmentally friendlySpecification:Item Type: Generator Automatic Voltage RegulatorMaterial: ABSSensor Input Voltage: 220/400VAC 1 phase 2 wirePower Input Voltage: 180~240VAC 1 phase 2 lineOutput Voltage: Maximum 90VDC at 240VDC inputContinuous Current: 6AIntermittent Current: 12A(10SEE)Generator Field Resistance: Minimum 10, maximum 100Brushless generator for 220/440VAC(programmable input).Package List:1 x Generator Automatic Voltage Regulator1 x User ManualNote:Diodes must be used to ensure that the AVR is not damaged.
