The hitherto electronic reversal circuits are based on the principle of electronic load relays, whereby a phase is interchanged only for the direction rotation change. The circuit takes place in contact less manner and without wear and tear in the zero-crossing. It's the best for the small motor 4 kW. Read more...

The new digital circuit DSH provides not only the possibility for smooth start of an AC-motor. DSH offers much more in different stages of extension.
Further on in another stage of extension it is possible to make an motor reversal with softstart. Up to 75 kW, the DSH-softstarter can be delivered including bypass-contactors for both directions of the motor. Read more...
