Feature: 1. PRODUCT INFORMATION: Potentiometer RP1 is of wire wound type, with resistance of 1KQ, model of WXD3 135 1K and power of not less than 5W. The wire diameter of E1 and 21 should ensure 8‑10A current, and the voltage regulator fuse should be 8A instant glass tube type. 2. CIRCUIT PROTECTION: The built in output voltage drops when the engine RPM drops, well protecting the circuit, use it with confidence 3. EXCELLENT PERFORMANCE: The AVR features stable and quick voltage regulation, take it for more efficient work 4. APPLICABLE GENERATOR: The AVR board is suitable for TZHY three phase brushless AC synchronous generator, check the model for better fit 5. EASY TO INSTALL: Comes with a compact size and a light weight as well, the easy installation can be quickly completed. Specification: Item Type: Automatic Voltage Regulator Mode: KXT 2WC1B Material: Aluminum Alloy Rated Voltage: 400V Maximum Allowable Current: 8A E1 21 Maximum allowable peak voltage 300V, maximum allowable average voltage 133V Steady state voltage adjustment vehicle: Less than or equal to ± 1% No Load Voltage Adjustment Range: 95 to 105% of rated voltage Applicable to TZHY three phase brushless AC synchronous generator. Package List: 1 x Automatic Voltage Regulator Note: When using this regulator, both ends of excitation winding E1 and E2 must be connected in parallel for 10 μ F/400V or 450V AC capacitor, CBB60 stable adjustment is recommended.
