Function: 1. Voltage Regulator: The voltage regulator is a sealed electronic device that stabilizes the brushless generator's output voltage by adjusting the generator's excitation current. 2. Stable in Operation: Ultra-low excitation voltage, fast response, more stable voltage. The main circuit uses industrial components with high stability, and the temperature drift is less than 0.05%. Multiple independent protection circuit designs ensure safety and reliability. 3. High Working Safety: Low-frequency protection and voltage slow build-up function, EMI suppression circuit, high-power 8A fuse protection. 4. Perfect Match: Perfectly fits 110VAC, 220VAC, and 400VAC brushless generators, the automatic voltage regulator facilitates operation. 5. Easy to Install: Lightweight and compact in size, the AVR allows for easy installation that can be quickly completed in minutes.
