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:
|
Load |
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.
5. Product Details:
The description of different parts of the product. The LCD dispaly pannel, the air switch, the omin-directional wheels, the heat dissipation holes, the lock.
Please see the back profile of this tabilzier. The heat dissipation holes are around three sides of it. So it has a good characteristic of ventilation.
