CHF100A series High Performance Universal Inverter

CHF100A series high performance universal inverter is the enhanced edition of CHF series, which is combined the advantage of CHF100 & CHE100. It adopts the DSP control system supplies sensorless vector control and V/f control. The performance is more perfect and stable. It is widely applied in Pump & Fan and some applications with high speed control accuracy, rapid torque response and high performance at low frequency.
