Vector Inverter (High Performance), AS500 Series

 Vector Inverter (High Performance), AS500 Series

The AS500 Series of high performance vector inverters combines speedless sensor vector control technology, closed loop vector control and torque control technologies. This high end inverter is reliable and flexible in application. We offer customized inverters for fans, water pumps, and other machines. Each of our frequency converters are designed to last over ten years.

1. Reliable safety features such as overload protection, current limiting functions, and password settings.

2. Efficient energy-saving operation and PWM dead zone compensation technology.

3. Fast response with advanced motor model control.

4. Strong grid adaptability. When the grid voltage changes, the output voltage is kept constant and can work in power failure.

5. Smooth track start

6. Multiple parameter settings for frequency, PID control, power-on and self-checking functions, and hopping frequency control.

7. Low noise and effective heat dissipation
