What's with the power saver on Taobao? What is the principle? Is it useful?

Principle of power saver: Real-time online detection of the working state of the motor, thus changing the input voltage. When it is detected that the motor is lightly loaded or the load is constantly changing, the voltage input to the motor can be adjusted within one hundredth of a second through the thyristor, so that the output power of the motor is just matched with the real-time load, thereby effectively reducing the power loss of the motor, improving the starting and stopping performance of the motor, and achieving the effect of saving electricity.

Advantages of energy saver:

1, the power saving effect is remarkable, and the power saving rate is as high as 10%-30%.

2. The product host (excluding switches, indicator lights and instrument wearing parts) is guaranteed for ten years and maintained for life.

3. Non-phase-controlled energy-saving technology does not produce higher harmonics, and the output end is always a complete sine wave, which has no pollution to the power grid and no interference to the wired and wireless signals of users.

4. Reduce system load and improve power supply system capacity.

5. Restrain surge (starting) current.

6, balance the interphase voltage, the equipment runs more stably.

7. Reduce the equipment temperature and prolong the service life of the equipment.

8, suppress harmonics and clutter, improve the efficiency of equipment operation.

9, maintenance-free, no need for special management.

Extended data:

With the development of science and technology and the rapid growth of social economy, various electrical appliances have entered thousands of households. Therefore, the load of household electricity is increasing, and the cost of electricity and maintenance and renewal of household appliances is also increasing. How to save electricity, reduce electricity expenses, protect household appliances and extend their service life has become an urgent desire of every family.

Ten key energy-saving projects were launched in the 11th Five-Year Plan, and two of them clearly pointed out that the building energy-saving design standards should be strictly implemented and the energy-saving renovation of existing buildings should be promoted. Promote energy-saving products; It also requires the use of energy-saving products in commercial buildings, office buildings, houses and public facilities. China only needs to invest 2.6 trillion yuan for energy-saving renovation of existing buildings.

The requirements of the country and the needs of the family have greatly promoted the R&D efforts of Rice Technology. The company's R&D team finally developed and produced the first high-tech, high-performance building/household energy-saving equipment in China, and obtained the national patent. The birth of building/household energy-saving equipment fills the gap in this market and is welcomed by real estate developers and middle-and high-income families.
