Moeller Soft Starter DS4 Range Controlled switching and starting Features Simple handling. Terminals similar to contactor. Mounting on top hat or DIN rails or fixing with screws. Can be grouped side-by-side. Degree of protection IP 20. Heat sink integrated into enclosure. Selective multi-voltage input for the control voltage. Status indication via LED. CE conformity. UL approval (File No. E236856).   Application Examples Three-phase resistive and inductive loads. Soft switching of motor starters in transport and conveyor belts. High switching cycles of motors in packaging machines. Silent switching of light and heating in buildings. Soft starting of pumps reduces the load on the entire installation (water impact). Solid-state switching of pumps in the extreme environments of chemical plants and filling stations. Fast and silent control in the buildings field with reversing function with lift doors, garage gates and conveyor belts in the cooling and checkout area. Smooth start that reduces wear on V-belts in fan drives.
