Selection of Inverter in Speed Regulation of Air-Blower and Pump

Using general-purpose inverter to control load of fan,pump can save energy effectively.When the general-purpose inverter is prepared for the existing motor,it is necessary to select the types of inverter according to the actual situation firstly,then it is important to calculate the rated value of inverter accurately,to achieve the best cost performance.The basic principle of selecting inverter shall be that the total current of load with continuous running does not exceed the inverter's rated current.
