Product Description
CHZIRI 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;
