The 220V single-phase variable frequency drive to 380V three-phase converter is an electrical device that converts the current of one frequency into the current of another frequency. There are strong demands on the inverter's technology and reliability because the AC900 has a 220V input and a 380V output, with variable voltages before and after conversion. Changing the speed of the motor feeding the pump and fan prolongs the equipment's service life.
