ABB 1SFA896105R7000 PSR9-600-70 Soft starter is a compact motor starting device designed to provide smooth acceleration and deceleration of three-phase induction motors. By progressively controlling the motor voltage during start and stop, it helps reduce starting current, mechanical shock and stress on belts, couplings, pumps and driven equipment. The PSR9-600-70 operates over a wide 208–600 V AC main voltage range and uses a 100–240 V AC, 50/60 Hz control supply. Its maximum rated operational current is 9 A. ABB India rates this model at 4 kW / 5 HP. The PSR series uses two-phase voltage control for soft start and soft stop and incorporates a built-in bypass, which reduces internal power losses after the motor reaches operating speed. Start and stop ramp settings are adjusted using three front-mounted potentiometers, and a normally open RUN relay output is provided for operating-status indication.
