Description features:A. Product Principle Household appliance always appears switch frequency,high-low frequency voltage at day and night ,current block in long-used time and heating of appliance.In view of this situation, we designs the new type of product. Compose of high-frequency and low-frequency network filtering in line network respectively, through overall portfolio, have improved significantly on the energy ,input power, input current, energy efficiency, power factor and other performance indicators of air conditioner, refrigerator ;control the inrush current and pulse voltage and high-low-frequency harmonic because of starting household appliances frequently; So that stable the high and low voltage and the current in different size relatively ,to achieve the purpose of energy saving, environmental protection, and protecting appliance. B. Features a) The suitable power is large. b)It is more fashionable,attractive and practical. c) It is not only energy-saving and environment protection but also ensure safety of appliance, it is a must for family in all seasons. C. Product Features a) To improve power quality of appliances, increase the capacity of electricity b) Impact line coke, maintain current flow c) Lower line temperature, reduce electricity waste d) Protect household appliances, extend life e) Save energy automatically and lasting , long time good effect D. Scope a) Each country, region, urban, rural families b) Small integrated power places E. Installation method a) Will be inserted the energy saver in the more using electrical appliances of power lines socket, after inserting, do not often pull out the energy saver so as not to affect effective time. b) General household use only one,large family can use two c) Comprehensive places can use a number of parallel F. Technical parameters a) Applied voltage:90v-250v b) Maximum Power:18000w c) Frequency:50-60hz d) Energy saving efficiency:10%-30%
