The power filter is an electrical device that effectively filters out the frequency point of a particular frequency or a frequency outside the frequency point of the power line. The function of the power filter is to obtain a power signal with a specific frequency by inserting a power filter in the power line, or after eliminate a specific frequency to get a power signal. Using this feature of the power filter, a square wave group or composite noise that passes through the power filter can be converted into a sine wave of a specific frequency.

20A high-power power filters such as Satons, UBS, inverters, etc. will generate a large number of harmonic currents. Such filters require the use of active power filters APF. APF can filter 2~50th harmonic current.

Principle: The power filter is a passive two-way network. It has a power supply at one end and a load at the other end. The internal circuit of the power filter, the principle of the power filter is an impedance-adaptive network: the greater the impedance adaptation at the input and output sides of the power filter and the power supply and load side, the more effective the attenuation of electromagnetic interference!

The power filter max power up to 4400W, and it operates at 2500W~3000W for a long time. The diameter of the electric mode coil is 1.4MM and the height is 31MM. Maximum current 20A, double-sided 1.6 tin plate!
