Installation Filters

Power Line Filters Overview

Filters in this catalogue have wide application in the EMC field where high performance is required.
They are ideal for filtering d.c. and a.c. mains services to screened enclosures against both incoming and outgoing noise and transients.

Standard Performance Range Filters

From screened rooms to industrial power equipment, uncontrolled radio interference presents a common hazard. This range of filters is designed specifically for use on single and three phase mains, and has all the advantages of using current compensating inductors.

Extended Performance Range Filters

This range of filters has been designed to meet the very highest insertion loss requirement of 100dB from 10kHz to 10GHz and features an extended low frequency performance to provide considerable filter attenuation at frequencies as low as 1kHz.

Low Leakage Range Filters

This range of single and three phase filters features a low leakage construction offering increased levels of safety. Applications include secure communications systems, computer installations, and portable screened enclosures. These filters are designed for use on mains supplies with a dedicated neutral.

Low Leakage Extended Performance Range Filters

Featuring full 100dB performance down to 10kHz, these proprietary single and three phase low leakage filters were originally developed to meet stringent requirements within modern military communications systems. However, with the increasing importance of high performance at low frequency and greater emphasis on increased safety, their applicability is now widespread.

Ultra Low Leakage Filters

A range of two and three phase filters offering ultra low line to earth leakage. The filters provide high attenuation from 100kHz to 18GHz suitable for use in TEMPEST and other secure information handling applications. The filters are designed without a neutral line for use within floating line applications and have line to earth leakage current minimised, to allow up to 5 filters to utilised in parallel and remain below 30mA.

Very High Current Range Filters

This range of filters has been developed for use on very high current three phase and neutral mains supplies. All filters employ MPE’s proprietary low leakage filter design incorporating current compensating inductors to provide very low heat dissipation and hence running costs.

Two Line DC Filters

These two line d.c. power line filters feature the full benefits of using current compensating inductors. They are housed in rectangular enclosures and are designed for mounting on a bulkhead. They are suitable for all voltages up to 250V d.c.

400Hz Range Filters

This range of filters has been specially designed for use on 400Hz systems and utilises capacitors with low loss dielectric material to minimise heat dissipation.

Clean Power Filters

The MPE Clean Power range of EMI filters have been designed to provide the most cost effective solution where performance beyond 1GHz is not required. The filters are bidirectional and have been designed to reduce equipment generated EMI from emanating into the environment as well as protecting the integrity of the installation against hostile incident EMI.High reliability and safety characteristics are inherent in the Clean Power range of EMI filters. The filters utilise MPE’s proprietary self-healing metallised plastic film feedthrough capacitors.

Fixing Kits – Power Line Filters

These high quality fixing kits have been designed to provide an RFI tight bulkhead penetration for cables to facilitate fixing of rectangular filters to bulkheads or walls of shielded enclosures.
