Air Con power supply


Control mode applies the voltage vector control technology, offers a high start torque and high voltage utilization.

The load transformation adopts the no-load transform mode to reduce the current surge, and lengthen the life of the device.

Output voltage is a boost up sine wave and it is benefit for extend the service life of motor.

It has the perfect protective function to the air conditioning unit and  the power source itself.
