High Current (Low Leakage) Standard Performance Range
This range of filters has been developed for use on high current three phase and neutral mains supplies. These filters employ MPE’s proprietary feedthrough filter design incorporating current compensating inductors to provide very low losses and heat dissipation, hence low running costs.
Insertion Loss Performance
Asymmetric attenuation shown as measured in 50Ω system, at all loading conditions, in accordance with CISPR-17.

Typical Applications
- Screened Rooms requiring low earth current leakage
- To achieve compliance to MIL STD 461 & DEF STAN 59 411
