Technical Parameter


Product Overview:

SST series soft starter is a good substitute for traditional startup (eg. direct startup, auto-decompression startup, star triangle startup). By reducing volume, weight, equipment loss , maintenance and installation costs it is much more economical than the traditional old start-up method concerning the integrated application cost. It can effectively reduce the surge or the voltage drop of the power grid as well as mechanical stress and abrasion when starting. Compared with auto-decompression start-up mode, it is more suitable for frequent start-up and shut-off operation, and can provide higher start-up torque and smoother start-up effect than star triangle start-up mode. What’s more, instead of six motor wires, only three rated motor outlets are needed, which connection is also more simple than star triangle start-up.

Product Features:

1. Timesaving, laborsaving and space saving due to needless installation of external bypass contactor.

2. SCR module is made by German SEMIKRON and the main control chip DP by Italian STMicroelectronics.

3. Elegant appearance due to wire drawing anodic oxidation technology, high-strength aluminum body, no corrosion with acid and alkali salt spray.

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

5. Be connected with no need to input the motor parameters, built-in intelligent procedures, or the preset parameters.

6. The volume of the body is still reduced by 60% compared to the same type of products founded in the market even it is integrated with bypass contactor
