Three-phase mains filter with small footprint

FMAD NEO is the name of the latest single-stage filter family for three-phase systems with a neutral line. Especially compact with high performance, the new filter series is suited for use in today's more portable industrial machines, designed to occupy less floor space in manufacturing plants. A wide temperature range extends its capabilities for use in many critical applications.

Three-phase control cabinets almost always have severe space constraints. SCHURTER addresses this problem with a completely new filter design, which is much more compact than older generations. The new, almost cubed, design makes optimum use of available space in the cabinet housing. Designed with the highest quality components, the filter attenuation remains very high relative to its more compact dimensions.

The new filter family is also suitable for devices with high EMC loads. Typical areas of application include converters for photovoltaic systems, battery storage units or charging stations for electric vehicles. These high-performance filters are also the first choice for modern frequency inverters for motor control.

The FMAD NEO filter series has screw terminals for safe and reliable wire terminations. A full metal flange guarantees a good earth ground connection upon screw mounting to the chassis. Six fixing holes are provided for the mounting itself, which allows both symmetrical and asymmetrical mounting.

The standard versions can be used over a wide temperature range from -40 to +100°C. The filters are designed for currents from 16 to 230A at an ambient temperature of 50°C. They are ENEC and cURus approved and recommended for applications up to 520VAC. The standard versions are designed for industrial applications with leakage currents <13 mA. Special versions for leakage-critical applications of less than 3mA are also available.

The completely redesigned models of the FMAD NEO family supplant SCHURTER FMAD filters. They offer at least identical performance with significantly smaller dimensions and weight, moreover the series is an ideal substitution for like competitor products.
