 Product Features

1. Built-in bypass contactor ( Timesaving, laborsaving and space saving due to needless installation of external bypass contactor.)

2. Top branded components (It adopts branded components like SCR module made by German SEMIKRON and the main control chip DP by Italian STMicroelectronics.)

3. Alloyed body design with high strength. ( Elegant apperance due to wire drawing anodic oxidation techonology, high-strength aluminum body, no corrosion with acid and alkali salt spray.)

4. Control unit with internal power-supply design (Control unit can be used easily without independent power supply or even with no three-phase four-wire power.)

5. Set-free rapid deployment ( Be connected with no need to input the motor parameters, built-in intelligent procedures, or the preset parameters.)
