Ultra thin design with all aluminum casing. Features a differential mode filter system with two differential inductors for suppressing mid to high frequency interference on the AC power supply. Equipped with three sets of common mode filters combined through X2 capacitors and common mode inductors, forming a three-stage common mode filtering system that effectively reduces noise. Provides effective suppression of fast transient burst interference with repetition frequencies in the thousands of hertz range. Four-stage EMI filter system ensures comprehensive protection. Input voltage: single-phase AC 110–250V Output voltage: single-phase AC 110–250V Rated load current: 6A–10A Input port: Three-wire 7.62mm socket Output port: Three-wire 7.62mm socket Function: First-level differential mode filtering and third-level common mode filtering, offering bidirectional EMI protection to reduce interference, enhance equipment stability, and extend appliance service life.
