DS7 easily fits in place of existing soft starters, wye-delta starters or across-the-line NEMA and IEC starters. The voltage ramp start method provides a voltage ramp to the motor for constant torque increase. Users set initial voltage values and the duration of the ramp to full voltage conditions. Soft Stop allows for a controlled stopping of load when a stop-time greater than the coast-to-stop time is desired; for high friction loads where a sudden stop may cause system damage.

The Soft starter DS7 is ideal for pumps, fans and small conveyor applications. It is a fully integral element in the xStart system. The DS7 replaces the mechanical contactor and extends the "motor soft start" function.
