APPLICATIONS

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. By using coupled choke designs, it has been possible to provide a good performance with comparatively low capacitance values and hence reactive current, but it must be remembered that at 400Hz, reactive current can be significant and this current has to be supplied by the generator as well as the load current.

Many 400Hz supplies have high levels of harmonic content. This can cause additional heating within filters, so if this is known to be the case, it is better to select a filter of higher current rating than would otherwise be required. In extreme cases of harmonic content, please contact our technical department for advice.

All MPE installation filters are tested using the test methods defined within the following standards and meet or exceed the relevant performance and/or safety criteria defined within these standards:

Mil-Std-220C

TRANSIENT SUPPRESSION

All types can be supplied with integral transient suppression fitted between each input terminal and earth.

Varistor rating : 150V a.c. 80 Joules (10/1000µs)

Other varistor ratings can also be supplied. To specify the transient suppressed version, suffix V is added to the filter part number (see ordering code).

TYPICAL INSTALLATION DETAILS

The standard cable entry consists of an end conduit entry hole on the filter input (supply) side and a base conduit exit hole on the output (load) side.

Filters can be supplied with other cable entry positions if required upon request. Please refer to Installation Details page.

To facilitate installation of these filters, separate fixing kits are available to suit bulkhead panel thicknesses up to 20mm. Please refer to fixing kits product page.
