China variable frequency drive - VFD, AC drive inverter, frequency converter and AC power source manufacturers.

Adjustable speed drive

adjustable speed drive
Most applications with electric AC motor require variable speed in different working periods, like injection mode machines and greenhouse, it's a waste if the machines running in full load all the time, the best solution for this applications is installing adjustable speed drive with variable frequency output to control the motor in variable speed to save energy. We are a professional supplier in automation control industries like variable frequency drive, inverters.
