EMC FILTER SOLUTIONS

FOR RAIL & TRAIN APPLICATIONS

TO SUPPORT COMPLIANCE WITH EN50121

Electromagnetic interference (EMI) and electromagnetic compatibility (EMC) are major concerns for the rail industry due to the increasing use of complex power electronics, switching devices & microelectronics used in rolling stock, equipment, & rail infrastructure.

The mandatory requirement that all new rail applications must comply with the relevant aspects of directive EN50121 regarding EMC results in the potential need for EMC filter & capacitor solutions specific to the rail industry.

MPE are specialists in the design & manufacture of high performance EMC filters and capacitors suitable for use in high reliability applications such as railways, military vehicles, defence, IT & telecoms. With more than 80 years proven heritage in this specialist field, MPE are the first choice for companies who require the most cost effective solution, quality product & technical support. MPE’s comprehensive standard products range from high performance feedthrough capacitors to high current power filters, with wide frequency spectrum characteristics in a choice of enclosure styles. As all key components are manufactured in-house, MPE have the capability to design & manufacture optimum cost-effective solutions to suit the specific application. MPE can provide solutions that deal with the three main aspects of the directive: the effect of the railway system on the surrounding environment, on signalling & communications equipment & the apparatus operating within the

environment. These include…… EQUIPMENT FILTERS : Particularly suitable for apparatus used within rolling stock are the

MPE range of equipment filters. For applications up to 15A, several ranges are available,

including a series specifically designed to suppress equipments powered by a switch mode

power supply, which in themselves require particular filter circuitry to deal with the emc issues.

Detailed explanation can be found in the product catalogue.

HIGHER CURRENT FILTERS : For rail applications that require higher current solutions,

MPE manufacture standard ranges of equipment filters in single & three phase series up to 100A. These filters incorporate feedthrough capacitors to give excellent high frequency performance, with bulkhead or chassis mounting for optimum mounting flexibility.

FEEDTHROUGH FILTERS & CAPACITORS : For rail equipments or applications that may

only require this type of solution - MPE manufacture a vast standard range starting from 0.5A to

500A, with various performance levels & covering the higher frequency spectrum (above 1GHz)

that EN50121 requires.

INSTALLATION FILTERS : For protection of rail infrastructure, communication installations,

substations, & other power related applications – MPE manufacture an extensive range of

single & three phase filters as well as signal, telecoms, and data filters to offer total protection

to the related environment.
