Main Features for ZJR2 series soft starter ZJR2 series soft starter can work with three-phase ,AC squirrel cage induction asynchronous motor ,The voltage is 320V~460V, 50HZ/60HZ and the current is 1200A and below . The soft starter is a device type .It's necessary to add breakers (short-circuit protection ) and AC contactor (Bypass) inside the cabinet . together with switches are made up of electric motor control circuit .
ZJR2 device type can work without three-phase AC motor in the process of starting too big acceleration torque, and power supply system plays a protection from excessive current harvest dynamic impact role, has the following characteristics:
1. 16 SCM control, intelligent all-digital display;
2. can be put into practice a soft starter control multiple motors;
3. Starting modes: Current limiting starter, Voltage ramp start , Kick start +current-limiting start, kick start +voltage ramp start . Current ramp start . Voltage current-limiting double closed –loop start .
4. free stop and soft stop , The stop time from 0 to 60 seconds can be arbitrary choosed .
5. Over current , Overload , Open phase, instantaneous stop and other fault protection .
with the flow, over loading, lack phase, instantaneous stop, and other malfunction protection;
6. Easy installation, simple operation, strong function and reasonable prices;
Scope of application for ZJR2 Soft Starter : ZJR2 series soft starter motor applies to centrifuges, blower, compressor, transport planes, mixer, rolling ball mill broken machines and mechanical equipment motor starter.
