Founded in 1974 we focused our work to power-conversion technology. We manufacture since 1978 frequency-converters for the speed control of 3-phase asynchron motors. Today we produce off-line frequency-converters in the power-region up to 7.5 kW in various versions. The main part of our products are custom-designs for special purposes. The range is starting at low-cost units for 150W up to bus-controlled units with a power of 7.5 kW.

We are also producing units with isolated low voltage outputs (48V) up to 3 kW and battery supplied drives up to 40 kW for boots and cars. For the battery-powered systems we are manufacturing chargers and capacity-monitoring parts.
