Ultra thin design with all aluminum casing. Features a set of differential mode filters and two differential inductors for effective differential mode filtering on the AC power supply, helping to suppress mid to high frequency interference. Includes three sets of common mode filters combined through X2 capacitors and common mode inductors to form a comprehensive common mode filter. The multi-stage (three-level) filtering design enhances noise filtering performance and helps suppress fast transient burst interference with high repetition frequencies. Four-stage EMI filter system provides bidirectional protection. Input voltage: single-phase AC 110–250V. Output voltage: single-phase AC 110–250V. Load rated current options: 6A or 10A. Input and output ports: three-wire 7.62mm socket. Offers first-level differential mode filtering and third-level common mode filtering to reduce electrical interference, improve equipment stability, and extend appliance service life. Note: Product appearance and color may vary slightly due to ongoing updates and manufacturing differences. Please consider this before ordering if specific appearance details are important. Type options: A (6A with shell), B (10A without shell), C (10A with shell), D (6A without shell). Color: As shown. Material: Aluminum. Package includes: 1 x EMC audio amplifier. No other items included. Note: Lighting and display settings may cause slight variations in color representation. Measurement tolerance: ±1–3 cm.
