Feature: 1. BRUSHLESS GENERATORS USE: This automatic voltage control board is designed for brushless generators, with the input voltage of AC160V to 260V. 2. PRECISE REGULATION: The generator auto voltage control board regulates and stabilizes the voltage precisely and stably, reliable to use. 3. EXCELLENT SEMICONDUCTOR: The automatic voltage regulator adopts mature semiconductor, makes ensure a positive voltage build up from the residual level. 4. FREQUENCY COMPENSATION PROTECTION: The board has built in frequency protection circuit that will reduce the output voltage when the engine speed drops. 5. PROFESSIONAL MODULE: The regulator is professionally manufactured, can be perfectly matched with the generator, has good wear resistance, easy to install. Specification: Item Type: Generator AVR Material: PC, pure copper Model: GAVR-10A Voltage Build Up: When the residual magnetism is greater than 4V 25Hz, the voltage will be built automatically Input Power: AC 160-260V 50/60Hz Frequency Compensation: Built in frequency protection circuit that reduces the output voltage when the engine speed drops Maximum Output Voltage When Inputting 220VAC: 70VDC, continuous output current 7A, maximum output current 10A.
