1P 220VAC 50/60 Hz16A EMI POWER LINE FILTER FOR RF SHIELDING ROOM
Power line filter's principle is an impedance adaption network: the larger the impedance mismatching between line filter input & output side and power & load side, the more effective the attenuation of electromagnetic interference (EMI). The specific working principle is as follows. After AC is rectified by diode, the direction is single, but the current intensity is still constantly changing. Generally, this ripple DC is not directly used to power supply. To make the ripple DC into a smooth waveform, one thing need to be done, that is filtering. In other words, the task of filters is to reduce the ripple in the output voltage of the rectifier as much as possible and transform it into near constant DC.

The commonly-used filter circuits of power line filters have passive filtering and active filtering. The main forms of passive filtering are capacitive filtering, inductive filtering and complex filtering (including inverted L-type, LC filtering, LC π-type filtering and RC π-type filtering, etc.). The main form of active filtering is active RC filtering, also known as electronic filters. The magnitude of the ripple component in DC electricity is represented by the ripple coefficient S: the larger the value, the worse the filtering effect of the filter.
