The FTF EMI power supply filter series includes general‑purpose, high‑performance, ultra‑high‑performance, three‑phase, and military‑grade filters. Each filter is designed to suppress both common‑mode and differential‑mode interference, offering low leakage current and compact construction.
The filters are rated for 115/250 VAC or 440 VAC, operate at 50/60 Hz, and meet EMC standards such as FCC Class B and VDE‑0871. They are suitable for switching‑mode power supplies, UPS systems, medical equipment, communication devices, inverters, and other power‑electronic applications. Technical data sheets, electrical schematics, and dimension drawings are provided for each model. This manual is written in Chinese.
| Rated Voltage | 115/250 VAC (or 440 VAC for three‑phase models) |
|---|---|
| Line Frequency | 50/60 Hz |
| Leakage Current | < 0.5 mA (115/250 VAC) or < 1.0 mA (high‑performance) or < 2.0 mA (440 VAC) |
| Test Voltage | Line‑Line 1450 VDC 1 min, Line‑Ground 1500 VAC 1 min |
| Temperature Range | -25 °C ~ +85 °C |
The standard filters have a leakage current of less than 0.5 mA at 250 VAC/50 Hz.
The filters meet FCC Class B and VDE‑0871 electromagnetic compatibility requirements.
Install the filter near the power entry, keep lead lengths short, ensure the housing is grounded, and maintain separation between input and output conductors.
