The Plug-in Single Phase AC Dual Stage Power Filter is a high-performance EMI filter designed to suppress electromagnetic interference (EMI) and radio-frequency interference (RFI) in 115/250V AC power lines. Featuring a dual-stage filtering architecture (common-mode + differential-mode), it effectively attenuates high-frequency noise (150kHz–30MHz) with insertion loss exceeding 40dB @ 1MHz. Compliant with UL 1283, EN/IEC 60939, and RoHS standards, it offers a compact, flame-retardant (UL94 V-0) design with plug-in or screw terminal connections. Ideal for industrial automation, medical devices, telecom, and sensitive electronics, it ensures stable power quality in harsh environments (-25°C to +85°C) while maintaining low leakage current (<0.5mA).
1. High-efficiency dual-stage filtering — common-mode and differential-mode two-stage noise suppression, insertion loss >40dB@1MHz, effectively filters out high-frequency interference.
2. Safe and reliable — compliant with UL/EN/IEC standards, flame-retardant housing (UL94 V-0), leakage current <0.5mA, suitable for sensitive equipment.
3. Compact Plug-and-Play Design — Modular plug-and-play design, wide temperature range operation (-25°C to 85°C), suitable for industrial, medical, communication, and other applications.
