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 design 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[...]
