New AVR BL4U BL4-U Automatic Voltage Regulator Stabilizer AC 3 Phase generators

New AVR BL4U BL4-U Automatic Voltage Regulator Stabilizer AC 3 Phase generators Product Overview The BL4U/BL4-U Automatic Voltage Regulator (AVR) is a precision-engineered stabilizer designed for Sincro HGI brushless three-phase generators. It ensures stable AC output by automatically adjusting the excitation current, maintaining consistent voltage levels even under fluctuating loads. Key Features Automatic Voltage Stabilization – Maintains a steady 220V/380V (50Hz) or 110V/220V (60Hz) output, preventing damage from surges or drops. Wide Compatibility – Specifically designed for Sincro HGI brushless generators (models BL4U/BL4-U). Built-in Protection – Safeguards against overvoltage, undervoltage, short circuits, and power surges. Durable Construction – Industrial-grade components ensure reliability in harsh environments (-25°C to 70°C). Easy Installation – Plug-and-play setup with clear terminal connections for quick integration. Technical Specifications Input Voltage Range: 170-260V (single-phase) / 300-450V (three-phase) Output Excitation Voltage: Up to 90V DC (auto-regulated) Frequency Range: 50Hz/60Hz (±5%) Protection Rating: IP20 (for dry, ventilated areas) Wiring: Screw terminals with high-temperature-resistant cables Installation & Maintenance Installation: Ensure the generator is powered off before connecting the AVR to the excitation circuit. Follow the provided wiring diagram. Maintenance: Periodically check for loose connections and clean dust from ventilation slots. Applications Ideal for industrial, commercial, and backup power systems requiring stable three-phase voltage regulation. Package Includes 1 × BL4U/BL4-U AVR Unit
