Semiconductor contactor and soft starter DS4

Application examples

Three-phase resistive and inductive loads Soft starting of motors in transport and mechanical handling systems High switching cycles of motors in packaging machines Noiseless switching of lights and heating in buildings Soft starting of pumps reduces the load on the entire installation (water hammer) Solid-state switching of pumps in the extreme environments of chemical works and filling stations Rapid and noiseless controls in buildings with reversing function on lift doors, barriers in garages and on conveyor belts in freezer and supermarket check-out operations Smooth start that reduces wear on V-belts in fan drives
