A. The main principle The energy saver developed by XINWEILI,is a latest achievement, which can improve power quality and performance, increase the proper power of compressor, and reduce startup current and running current, achieving the purpose of energy-saving. What is more, compared with other control methods of energy saver for air condition, it does not only have any impact on cooling capacity and cooling capacity but also it is more practical. B. Product Features a) Absolutely do not affect refrigeration and heating temperature b) Absolutely do not change the original operation of compressor c) Absolutely do not change the original habits of users d) Absolutely do not move any parts of air condition C. Scope Apply to any places and suitable for 1P--3P of one-phase split air condition. D. Installation method Plug the plug of air condition into the surface of socket of energy saver, and then plug the plug of energy saver into the original power socket of air condition. E.Technical parameters a) Voltage: 220V?0% b) Frequency: 50HZ c) Power: 3000W d) Energy saving efficiency: %10-%15
