China Chziri Soft Starter Controller COM Control Electric

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;
ZJR2 Series Soft Starter motor applies to centrifuges, blower, compressor, transport planes, mixer, rolling ball mill broken machines and mechanical equipment motor starter.
