Key Product Features

1. Single-Phase 220V Dedicated Design, Perfect STC Brush Generator Compatibility

    

   Consistent with original wiring terminal definition, plug-and-play installation without complicated circuit modification, greatly shortening equipment maintenance downtime.
2. High Precision Voltage Regulation Performance

    

   Voltage regulation accuracy reaches ±1%, effectively suppress instantaneous voltage surge and drop caused by sudden load change, avoiding electrical equipment burnout.
3. Large Thickened Aluminum Alloy Heat Sink

    

   Fast heat dissipation during long-time high-load continuous operation, preventing the AVR module from overheating burnout and extending service life.
4. Wide Excitation Input Voltage Range (20~130VDC)

    

   Compatible with different residual voltages of various single-phase brush generators during startup, ensuring reliable voltage build-up and smooth generator startup.
5. External Manual Voltage Fine-Tuning Potentiometer

    

   Supports ±10% output voltage adjustment, which can flexibly meet different regional single-phase voltage standard requirements.
6. Insulating Glue Sealed Circuit Board Technology
   
   Dustproof, moisture-proof, anti-vibration and anti-electromagnetic interference, no voltage drift after long-term continuous operation, suitable for harsh outdoor working conditions.
    

Common Equipment Failures Solved

• Generator single-phase output voltage unstable, sharp voltage fluctuation when switching load
• Overvoltage fault frequently burns light bulbs, household appliances and small precision electrical equipment
• Undervoltage leads to equipment startup failure, weak motor operation and frequent shutdown
• Original AVR burnout results in no voltage output, generator cannot supply power normally
• Long-time running causes voltage drift, unable to maintain rated 220V stable output voltage
