3. Major Parts and the Functions


Name Function
Copper coils (Regulating coils) Adjusting the output voltage automatically
Aluminum coils (Compensating coils) Compensating the voltage automatically
1017 Carbon brushes Helping to regulate voltage
Servo motors Facilitating the rotation of carbon brush and so as to regulate voltage quickly
Circuit borads Controling three phase voltage independently and precisely
Enclosure Protecting the major parts of this stabilizer effectively
Omni-directional wheels Making movement of the machine more easily


4. Capacity Selection:


Please have a look at the following chart below first:



 Electrical Equipment Start Impact Rated Capacity of Stabilizer
Capacitive load Computer, TV, refrigerator, fluorescent lamp, mercury lamp etc. 1.5-2 times 1.5-2 times of the capacity of your equipment
Inductive load Air conditioner, pump, air compressor, machine tools, printing machines etc. 3-5 times 3-5 times of the capacity of your equipment


From this chart, you could see there are two kinds of loads, capacitive load and inductive load. When you want to buy a stabilizer, firstly, identify the rated capacity of your equipment. In other words, please know whether it's a capacitive load or an inductive load. Becuase the start impact of electricity is different. 


If you do not know to what type your equipment belongs, please buy a stabilizer of which the capacity is at least 5 times of the rated capacity of your equipment.
