Satronix is the manufacturer of 2-phase motor soft-starter or soft off. The product 2-phase motor soft-starter or soft off is used for single and three phase motors up to 11 kw. 2-phase motor soft-starter or soft off is available with adjusted ramp up, ramp down time and starting torque. 2-phase motor soft-starter or soft off has a setting through potentiometer and the Setting through potentiometer contains simple assembly and startup. The salient features of the 2-phase motor soft-starter or soft off:
Soft startup and run down with voltage ramp Integrated bypass contact for minimizing power Loss

Economical, analog type controller

20 percent reduction in starting current. Energy saving through reduced peak kva

It steplessly controls the voltage supply to the induction motor during the starting phase. In this manner the machine is gently brought up to load condition.

Mechanical drive components are better protected against wear. As result maintenance costs and stopping time are all reduced.

Reducing staring drive torque minimizing stress on motor berings, drive belts and chains.

Elimination of high current transients when a 3 phase motor switchs from star to delta
