No phase order required for the power.

Double insulation of the power prevents control parts from all kinds of disturbance.       

Soft start can provide smooth and step less start processing, low the start current and meanwhile prevent the line from disturbance.       

Improve the efficiency by limiting the disturbance from current surge, reduce starting torque, and set the upper limit of current so as to be used in the occasion with limited capacity of electrified wire netting.       

Special design of double protective loop has protection function against loss-phase, over-load, short-circuit and over-heat.       

Prolonging the shut-down time to relief load shifting and water-hammer effect during shut-down, soft stop time is adjustable.
