Product description

1. Main Features:

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 arbitrarily 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;

 

2. Application scope: 
ZJR2 series soft starter motor applies to centrifuges, blower, compressor, transport planes, mixer, rolling ball mill broken machines and mechanical equipment motor starter.
