Intelligent On-Line Type Motor Soft Starters/Intelligent Motor Soft Start Cabinet

Code and implication

Main technical data

Normal operating conditions

Power supply:three phase AC power from system,self-prepared substation, diesel generator,also we can make the starter with rated voltage 110V-1140V±20%,50Hz or60Hz according to demand,the capacity of power supply must meet with the requirement of starting motor.

Applicable motor:three phase squirrel cage asynchronous motor,rated power of motor must not exceed the rated power of soft starter.

Startup freq:not requested, determine according to the loading status.

Cooling mode:forcedly wind cooling

Protective grade: IP20

Ambient conditions: altitude less than 4000m, ambient temperature: -20℃~+40℃,relative humidity less than95%,the working site shall have no dew,no flammable,explosive, corrosive gas, no conductive dust,well ventilated indoor, shake less than 0. 5g.

Application

Online intelligent soft starter for motor adopts digital control,based on MCU,choose the controllable silicon module as execution element, and perform full auto control on the motor. It is suitable for the various squirrel-caged asynchronous motors, make the motor able to start smoothly at any working status,protect the driving system, reduce the surge of the starting current on system,and ensure the motor reliably being started.The function of softly and smoothly stopping the motor can effectively solve the surging shock due to inertia,eliminate the inverse inertia impact of the driving system,which can't be solved by traditional starters.Digital soft starter has complete protection functions,extend the servicing life of the system,reduce the cost for constructing the system, improve the reliability,absorb the various functions from all starting devices: it is the ideal substitute for the old star-delta starter, self-coupled voltage reduction starter and etc.
