Typical Applications
●Water pump
Using the soft stop function, the water hammer phenomenon of the pump is relieved when the pump is stopped, and the
cost of system maintenance is saved.
●Ball Mill
Using voltage ramp to start, reduce the wear of gear torque, reduce maintenance workload, save time and save money.
●Fan
Reduce belt wear and mechanical shock, saving maintenance costs.
●Compressor
The use of current limiting realizes smooth starting, reduces motor heating and prolongs service life.
●Crusher
Using locked-rotor protection and fast protection to avoid mechanical failure or blockage causing the motor to overheat
and burn.
●Conveying machinery
Realize a smooth and gradual starting process through soft start, avoid product displacement and liquid overflow.
Use and environmental conditions
●Main circuit power supply: three-phase AC 380V (- 10%, + 15%), 50Hz±0.5%
Note:The above data only applies to this manual
●Control circuit power supply: built-in AC380V 50Hz
●Applicable motor: general squirrel-cage asynchronous motor.
