Extended Performance HEMP & IEMI Filter Range

MPE HEMP Prot Ext Performance A

DESCRIPTION

A range of extended performance HEMP filters meeting the pci requirements of Mil-Std-188-125-1 and -2 and Def Stan 59-188 parts 1 and 2 for E1 and E2 pulses but having increased insertion loss performance for applications where additional performance is needed beyond just HEMP requirement. All lines have individual input inductors to offer superior transient handling performance and also coupled inductors to offer superior continuous wave EMC performance in a small package. All lines feature high-energy varistor transient suppressors.

All MPE HEMP 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-188-125
Mil-F-15733
Mil-Std-220C
CISPR17:2011/BS EN 55017:2011
UL1283
LVD 2014/35/EU
USACE 13.27.54.01.
UFGS 13.49.20.01.

FEATURES

  • 250V/440Vac with 6A – 400A current ratings
  • Single or three phase applications
  • Utilise MPE self-healing feedthrough capacitors for significantly improved reliability
  • Significantly smaller & lighter than traditional solutions
  • Single line input inductors for pulse handling
  • High energy transient suppressors for high reliability
  • UL94-V0 insulating materials used
  • Complies with IEC 950 requirements
  • Very low residual pulse current – high safety margin
  • Coupled inductor for high insertion loss
