single phase \ three phase E-Softstarter

Compact steady structure DIN rail mounting,easy to install and fix Centralization adjustment style switches

The  E-06...45  series is a digital micro softstarter which has specially designed for zhe single-phase or three-phase squirrel-cage motors with the  functionsof soft-start and soft-stop,adjustable time of soft-start and soft-stop and initial voltage of soft-start can be adjusted .It greatly reduce the shocks of engine torque and electrical current when zhe motors stared us a result ,the motors and  grid are kept in safety .It could be widely used in various control system of mini-type motors such as air condition,refrigerator freezer and pump,thereby zhe customer decrease the demand for quality  of gaid,reduce zhe load of gaid and prolong the running life of appliances.

This motor controller is intended to be used to soft start/stop 3-phase squirrel cage induction motors and thereby reduce the stress or wear on gear and belt/chain drives and to give smooth operation of machines. Soft starting and or stopping is achieved by controlling the motor voltage. During running operation the semiconductor is bypassed by an internal electromechanical relay. The initial torque can be adjusted from 5 to 50% of the nominal torque. The soft-start time can be adjusted from 0.5 to 10 s and 0.5 to 20 s for the soft-stop respectively A green LED indicates supply. The yellow LED is flashing during the ramping up or down. After the ramping when the semiconductors are bypassed the yellow LEDlights constantly. Alarm handling:Over temperature: The HPISE will not start if the heatsink has an internal temperature which is exceeding approx 100%. When over temperature occurs while the softstarter is not ramping(1) or while the bypass relays are activated(2) the following will happen:1) The softstarter will not ramp up and alarm relay is deactivated (contact open) - Reset takes place when the temperature drops below the critical level and only if the supply is interrupted and reapplied.2) The alarm relay will deactivate (open) to indicate fault and when the softstarter is not ramping, the softstarter will react as described in 1).
