New easy-to-install filters for IT system security

11 May 2014

To prevent the covert interrogation of conducted lines, MPE has introduced a new range of plug-in TEMPEST filters in 1-, 2- and 4-socket and inline versions that offer high insertion loss performance across a very wide frequency spectrum.

They are designed to the IT equipment safety standard EN 60950-1. Requiring no electrical contractors for their installation, these filters could therefore not be quicker, easier or simpler to deploy to meet an immediate need.

Over 300 units in different versions with different current ratings have already been supplied for UK sites of the Ministry of Defence, who immediately recognised the advantages of the new product.

Fully compliant with NATO SDIP-27 Levels B and C, MPE’s 250Vac, 50/60Hz, pluggable TEMPEST filters cater for 6A, 13A and 32A currents. The units provide EMI suppression across the full frequency spectrum. Accordingly they meet the TEMPEST protection standards applied to individual pieces of equipment of 60dB insertion loss performance over frequencies from 100kHz to 1GHz.

The 6A and 13A types of connection unit feature 3-pin plug input and socket outlets to BS 1363, whilst the 32A comes as standard with an IEC 60309 Commando connector input and BS 1363 socket outlets. Alternatively terminated filters, such as IEC, Powercon and Schuko, are easily supplied upon request.

The new units, housed in durable stainless steel enclosures, are significantly smaller and lighter than traditional TEMPEST filters.
