intelligent 380V squirrel cage motor power saver

 

control motor always move in most economic power save way, specially for light load and variable load squireel cage motor, high power save ability, light load can power 50% power

 

RANGE OF APPLICATION:

Widely used in  industried such as cement, construction materials, chemical industry, iron and stell, metallurgical and mine, etc,

 

OPERATING PRINCIPLE

 WDJ series of intelligent motor power saver gathers the current and voltage signal from the stator loop of the motor ,to control the conducting state of the three-way bi-directional silicon control through special transformation process, so as to control the starting current of the motor and input power of the motor in operation, realize the function of constant current soft start of motor,

automatically tracing the changes in the load of motor , and automatically adjust the input power  to realize the objective of save energy/ reduce consumption.

 

 CHARACTERISTICS:

remarkable power-saving effect:  the unload power-saving rate can reach up to 50|%

 

three starting mode: pulse jumping starting, constant current soft starting, and voltage slope starting

two stop mode: free stopping and soft stopping

 

It has function of remote control,DCS interface, and RS485 interface

 

main protective function: current amplitude limiting protection, open -phase protection, overheat protection, electric protector, human-machine interface, keyboard operation...

 

air purity requirement: without corrosive gas and conductive dust

two stop way : free stop and soft stop
