Three Phase Low Voltage AC drive

The Low Voltage (LV) three phase 380V AC drives supplied by us inherited our old generation version's compact design and integrated advanced technology for new features, like tracking the electric AC motor speed in real time, automatic running in instantaneous power off, it's a very useful function in unstable power supply environment. Dynamic current control and output high torque under very low frequency. Maximum power is up to 500kW.
