Datasheet

SCHURTER extends its successful family of chassis mounted filters for 1-phase systems, FMAB NEO with the new series FMAB HV. It is suitable for applications up to 277VAC as well as 400VDC. In North America, there are various 1-phase applications in the 3-phase 480/277VAC network. 400VDC is often used in modern data centres with DC power supply. The single-stage filter series combines a compact design with a high level of performance.

With 277VAC and 400VDC approval, the new FMAB HV filter family offers the greatest possible flexibility for various applications. Today, more and more mixed AC and DC power supplies are used for better energy efficiency and/or improved reliability. In these applications, the filter can be used on both the AC and DC sides.

The new filter series has a shiny steel housing with a closed filter base. This effectively shields the filter, no matter how it is mounted. The filter series is particularly suitable for devices with high symmetrical interferences, such as devices with semiconductors, which regulate high outputs (e.g. commercial coffee machines, hot water dispensing machines, and all types of industrial electronics). Due to their compact design, the filters are also well suited for medical and household appliances.

The filters are available with quick connect terminals 6.3x0.8mm. They have a metal flange for easy mounting on the chassis. The entire filter family can be used over a temperature range from -40°C to 100°C.

The series is designed for currents from 1-20A at 277VAC/277VDC according to IEC standard and 277VAC and 400VDC according to UL/CSA standard. It has ENEC and cURus approval and is suitable for applications according to IEC 60950.

For medical devices according to IEC/UL 60601-1, variants with low leakage currents less than 80μA (M80) or without leakage current less than 5μA (M5) are available.

Versions with built-in varistors for effective overvoltage protection are available on request.
