Soft Start and Soft Stop. - When starting, an AC Induction motor develops more torque than is required at full speed. This stress is transferred to the mechanical transmission system resulting in excessive wear and premature failure of chains, belts, gears, mechanical seals, etc. Additionally, rapid acceleration also has a massive impact on electricity supply charges with high inrush currents drawing +600% of the normal run current. The use of Star Delta only provides a partial solution to the problem. Should the motor slow down during the transition period the high peaks are repeated and can even exceed direct on line current. Powerboss provides a reliable and economical solution to these problems by delivering a controlled release of power to the motor, thereby providing smooth, stepless acceleration and deceleration. Motor life will be extended as damage to windings and bearings is reduced

Soft Start and Soft Stop is built into all 3 phase units, providing controlled starting and stopping with a selection of ramp times and current limit settings to suit all applications.

• · Less mechanical stress .
• · Improved power factor.
• · Lower maximum demand.
• · Less mechanical maintenance.

A ready to run 415V IP55 enclosed soft starter for, “3 wires in 3 wires out” fixing, incorporating all the necessary control gear is available, usually ex stock for up to 55kW and up to 110kW. Larger sizes up to 650kW built to order.
