Santa Rosa, California, May 06, 2019 SCHURTER extends its successful family of EMI filters for 1-phase systems with its new FMAB HV series. The new filter is suitable for applications requiring AC voltages up to 277 V, such as 1-phase of the 3-phase 480/277 VAC wye system, typically used for lighting applications in North America. It is also rated for 400 VDC, a power infrastructure increasingly common in data centers and equipment therein according to IEC 60950. The filter provides a high level of performance in a small compact package.

Today, there are more and more mixed AC and DC power infrastructures used for the purpose of energy efficiency and/or improved power reliability. In these applications, the FMAB HV enables filtering on both the AC and DC sides of the power stream, albeit connected via the mains directly, before and after conversion, or stepped down for use at 250 V. Due to its high symmetrical attenuation, the filter series is particularly suited for devices using semiconductors, which regulate high outputs (e.g. commercial coffee machines, hot water dispensing machines, and all types of industrial electronics). Furthermore, the compact fully enclosed housing provides optimized shielding through a very stable, flush mounting. Low leakage M5 and M80 variations are available for medical applications according to IEC/UL 60601-1.

The FMAB HV offers a current range from 1 A to 20 A at 277 VAC / 277 VDC according to IEC standard, and 277 VAC and 400 VDC according to UL/CSA standard. It has ENEC and cURus approval. The filters are available with quick connect terminals 6.3 x 0.8mm and are screw mounted to the chassis. Temperature range is from -40 °C to 100 °C. Versions with built-in varistor for effective overvoltage protection are available on request.

Pricing for the FMAB HV starts at $16.88 per each for the standard version in 50 piece quantities. Packaging various depending on rated current.
