Application scenarios and usage effects
This type of energy-saving device can be installed wherever three-phase AC asynchronous motors are used. For example, in industrial and mining enterprises such as steel mills, foundries, chemical plants, machine tool factories, paper mills, distilleries, flour mills, cement plants, textile factories, petroleum machinery, oil fields, construction machinery, diesel engine factories, refractory material factories, coal mining machinery, bearing factories, automobile and tractor factories, gold mines, paint factories, brick factories, restaurants, etc., three-phase AC asynchronous motors used in refrigeration systems, lathes, milling machines, planers, grinders, punch presses, hole boring machines, flour mills, large mills, mixers, shearing machines, forging presses, friction presses, steel mills, ball mills, fans, water pumps, air compressors, oil pumps, wire drawing machines and other equipment can all be installed with this type of energy-saving device.

On average, the current is reduced by about 20%, and the energy-saving and consumption reducing effect is significant.
2. Improving the power factor of the motor can achieve a power factor of 0.95 or above.
3. Increase transformer capacity by 20% to 35%.
4. Reduce the cross-sectional area of power supply and distribution lines by 10% to 30%.
5. Improve power supply quality and extend the service life of electrical equipment.
6. It has functions such as reducing motor starting current, anti surge, explosion-proof, and automatic discharge.
7. Environmentally friendly products with no environmental pollution.
8. Flame retardant insulation shell, safe and explosion-proof, no harm to personnel.

Installation and Connection
The energy-saving device should be installed at the corresponding position at the lower end of the AC contactor or air switch of the starting motor. When wiring, it should be as close to the motor as possible or connected to the main circuit of the motor junction box. The specific wiring diagram is as follows.


The energy-saving device can be installed and used independently, or several independent energy-saving devices can be connected in parallel with a busbar. When using a power saver, connect the three output terminals of the power saver according to the method shown in Figure 1 or Figure 2; When multiple independent energy saving devices are used in parallel, each independent unit should be connected in parallel using a busbar, and then wired as shown in Figure 1 or Figure 2.
