Benefits from PowerBoss
These machines can benefit greatly from Powerboss. The softstart function will reduce both starting current drawn by the motor and mechanical strain on bearings, gears, belts and etc. The reduction in starting current will also increase motor’s life.
The optimization function will reduce the power supplied to theMotor without changing its torque and rpm. Reducing the power supplied tothe motor will significantly reduce the heat, vibration and noise. Reducing wasted energy will also reduce the maintenance cost and production downtime.
