The document describes the EMC-Power Line Filters product line from Schurter, including standard and medical types, with different features and characteristics, suitable for various applications.
The FMW2 series are all‑purpose EMC‑Power Line Filters designed for 1‑phase systems. They protect equipment from mains interference and attenuate emissions generated inside the equipment. The filters are intended to be mounted as close as possible to the mains input.
The handbook lists technical data such as nominal current, rated voltage, test voltages, leakage current and MTBF, and includes optional versions like a medical variant with very low leakage current and a version with a ZNR‑varistor for over‑voltage protection. Order numbers and key parameters are provided for each filter size.
| Nominal current | 1‑10 A @ 40 °C |
|---|---|
| Rated voltage | 125/250 VAC 50/60 Hz |
| Test voltage (UN) | ≈ 2.7 kVDC, 2 s |
| MTBF | > 200 000 h @ 40 °C |
The filters are rated for 1‑10 A at 40 °C.
They conform to EN 133200, UL 1283 and IEC 60950.
Yes, the Medical M5 version has leakage current below 80 nA.
The MTBF is greater than 200 000 hours.
