1) Ultra thin design, all aluminum casing. 2) A set of differential mode filters and two differential inductors are used to perform differential mode filtering on the AC power supply to suppress mid to high frequency interference. 3) Three sets of common mode filters are combined through X2 capacitors and common mode inductors to form a common mode filter. Due to the use of three-level (also known as three-level) filtering, the effect of filtering noise is better. For certain user sites with fast transient group pulse interference with a repetition frequency of several thousand hertz The problem of disturbance can have a suppressive effect.<br><br>Four stage EMI filter Input voltage:single-phase AC 110-250V Output voltage:single-phase AC 110-250V Rated current of load:6A-10A Input port:Three wire 7.62 socket input Output port:Three wire 7.62 socket output Function:First level differential mode filtering+third level common mode filtering, bidirectional EMI filtering, to prevent interference, extend the service life of electrical appliances, and increase equipment stability Tips:The product may be updated constantly, The Actual Product May Have Slight Differences Or Color Differences the color and appearance may be changed, please don't mind.
