Energy saver soft starter

Energy saver soft starter with current limit soft start facility is used with induction motors for obtaining soft start, energy saving and protections, for overload and single phasing. The induction motor draws full magnetising current when the rated voltage is applied. At lower loads also the same magnetising current is maintained, although not required. This results in the iron and core losses being higher and power is wasted away as heat at lower loads, reducing the efficiency, considerably. Also the power factor is low, as reactive current higher than required is drawn from the supply. Hence it is possible to save energy and improve power factor by reducing the voltage to the optimum value. When the motor connected to the energy saver soft starter is switched on, a gradual start is obtained with a fairly low starting current. After achieving soft start, the starter automatically and continuously adjust the voltage to obtain optimum operating voltage based on load. Other advantages include reduced motor temperature and increased life, jerk free starting, etc.
