Noise is filtered better due to the use of three-stage filtering Three set of common mode formed by combining 2 capacitors and common mode inductors Thin design, all-aluminum housing Function: Firstly stage differentials mode filtering Third stage common mode filtering, bidirectional Electromagnetic Interference filtering, interference, prolonging the service life of electrical appliances, increasing the stability of the equipment 1 set of differentials mode and two differentials inductors used for differentials mode filtering of power supply to suppress mediums and high frequency interference
