Brand Name: CHZIRI
Model Number: ZJR2, ZJR2 Series
Place of Origin: Zhejiang, China (Mainland)
Soft Starter Description
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 .
ZJR2 series soft starter are in the process of motor starting and running a perfect protection function, adopted the closed loop control, greatly improving the stationarity of soft starting torque of the motor
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 .
Main Features for ZJR2 series soft starter
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;
