1. Output low-voltage / High-voltage protection    
  Built-in low-voltage / high-voltage detection and protection circuit. Protection points  adjustable. When output

  voltage is out of range, protector will cut off output and give warning (LED Blinking).

 2. Open-phase protection
  Built-in Open-phase protection circuit. When Open-phase happens, protector will cut off  output and give

  warning (LED Blinking).

 3. Overload protection
  Built-in overload protection will protect this AVR automatically even the output was short  circuit.

 4. Superior monitoring system  
  Even with the mentioned built-in protection inside, we integrated a Superior monitoring  System to give double insurance of the performance.

 5. Soft-output function
  Built-in Soft-output function, when started or resume form power outages, output voltage will  be started from a low voltage to avoid damage to equipments.

 6. Free form Voltage-Drop
 Dual-stack design. Even a single phase loading is imbalance up to 50%, Voltage-Drop will  not happen. So it is ideal for motor, servo motor and other launch-frequent equipments.  

 7. Pure Linear Voltage adjustment
  Linear Induction control, no voltage ladder. (Relay type and servo motor type can only give ladder voltage output)

 8. Contactless design
 No contact surface in the machine, no Arc.

  9. Wide input voltage range
 ±15% or ±30% input voltage range.

 10. Modular design    
 Complete Modular design, for easy after sales services and debugging.

 11. Fully isolated, manual bypass function
 For maintenance or repairs, bypass can be activated manually (short-circuit and overload protection are still

on guard)

 12. High temperature detection
 Built-in temperature detection circuit, when main coils are overheating LED blinking will be activated, giving message that maintenance or replacement of the mail coils required.

 13. Misoperation prevention design
 To prevent misoperation, double lock system was applied in this AVR. Only press the two power buttons in the same time can the machine be started or shut down.    

 14. Excellent loading / overloading ability    
 100% load for continuous operation, transient inductive loading is also welcome.  

 15. Better efficiency, excellent characteristics
 high efficiency low iron loss Silicon steel was applied, the base of lowest reactive loss and active loss.

 16. Compact size design
 The high-strength structural design gives a smaller size and less weight.

 17. Seriously selected industrial-strength components, work for more than 10 years
 Lifespan can be more than 10 years. All components are selected for years, transient high voltage is welcome.
