EM-GJ3-series Soft Starter

EM-GJ3-series Soft Starter is a new type start-up equipment which integrates electric force and electronic techniques, computer technique and modern control theory. It is the new generation product to replace the conventional Star-delta Starter, Self-coupling voltage-drop Starter and Magnetic control voltage-drop Starter.

Description:
1: Advanced soft starter type: & quot;voltage control type& quot; and & quot;current limiting type& quot;.
2: capacity to motor effectively, so it could save the cost.
3: Intelligent, digital and single chip control.
4: Man-machine conversation function.
5: Delay starting function. Operation current displayed.
6: Failure self-diagnosis.
7: Natural wind cooling. Space saving.
8: Can reduce the starting stress of motor and other loading equipments, so that lengthen their service
life.
9: The function of soft stopping can solve effectively the surging problem of inertia system when
stopping.
10: The perfect and reliable protection features, can give the effective protection to the operator& acute;s
safety as well as the motor and matched equipments. Such over voltage; over current, over load,
over heat, short circuit , lower voltage, input or output phase failure; three phase imbalance,
starting time over long protection etc.
