soft starter

Nowadays, three-phase motors represent the most favored type of drive concept. Direct starting or star-delta starting is, in many cases, not the best solution. Such methods often result in unpleasant side-effects such as mechanical impacts inside the machine or voltage dips in the power supply system.

Our new SIRIUS family of soft starters is a comprehensive range of products covering all the standard and high-feature motor-starting applications. The advantages of soft start-up and smooth ramp-down with these devices can therefore be exploited in the most varied of applications for simple and economically efficient machinery and equipment layouts.
