MPE Very High Current Installation Filter A

 

 

 

 

 

 

 

 

 

 

 

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 performance categories are offered both providing full insertion loss with or without load. These filters are ideal for use in EMP protection systems and in TEMPEST applications.

Customised terminal chambers can be supplied to interface to individual installations.

All types are available with transient suppressors fitted to the input terminal busbars.

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-F-15733
Mil-Std-220C
CISPR17:2011/BS EN 55017:2011
UL1283
EN60950/IEC60950

Note: Extended performance filters are supplied as two interlocking parts for ease of handling and installation.

Note: “C” case styles are not offered for 1600A and 2400A filters as it is more practical to use a filter with case style “A” and penetrate the shield via the terminal enclosure.

TRANSIENT SUPPRESSION

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

Varistor rating : 2750V a.c. 360 Joules

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

After mounting, for safety and for shielding purposes the filter terminals must be enclosed by screened covers. Custom terminal chambers and mounting frames can be supplied if required.

These filters have integral blind inserts to facilitate mounting and screening of terminal enclosures. They must not be used to support the weight of either the filter or the terminal enclosure.

Because of the very high current rating of these filters, it is important that all conductors pass through a common cable entry point in the shield to avoid eddy current heating effects.

ORDERING CODE

DS XXXXX / X / X e.g. DS23973CV

Filter Part Number

Suffix C for standard cable entry
For other cable entries, see Installation Details page

Add suffix V for transient suppressed filter

STANDARD PERFORMANCE FILTERS

Transportation holes may be used for connection of a separate safety earth, if required.

EXTENDED PERFORMANCE FILTERS

Note: Extended performance filters are supplied as two interlocking parts for ease of handling and installation. An interface gasket is supplied to join the two sections.
