A soft start and soft stop is incorporated on all 3 phase Powerboss units. The robust soft start, capable of over 250 starts per day, provides smooth, stepless acceleration which dramatically reduces stress on mechanical transmissions. By eleminating high inrush currents, maximum demand greatly reduced. Powerfactor will also be improved.

Soft stop provides a gradual deceleration, particularly suitable for fluid pumping where abrupt stops create torque transients, which cause harmful water hammer effects. Where appropriate, Powerboss can also be programmed to detect long periods of 'no load' at which pointthe motor can be automatically swiched off adding further significant
benifits.

In short Powerboss will give the motor theexact amount of power it needs at any instant in time - no more - no less!
