Standard Performance HEMP & IEMI Filter Range

MPE HEMP Prot Standard Performance A

DESCRIPTION

A range of 2 line and 4 line (single & three phase) Power Line HEMP filters independently tested and certified as meeting and exceeding 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. All lines are individually filtered and feature inductive input to offer both good continuous wave EMC performance and superior transient handling performance even on supplies with low source impedance. All lines are fitted with high-energy 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 – 1200A current ratings
  • 2 or 4 individually filtered lines
  • Utilise MPE self-healing feedthrough capacitors
  • Significantly smaller & lighter than traditional solutions
  • Much lower heat dissipation than traditional solutions
  • 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

** 400A filters additionally have lifting lugs protruding 65mm beyond each end of the filter and 8mm beyond each side to
aid mounting. Lug hole size 22mm. Please request drawings P828749 or P828750 for full dimensions of 2 line and 4 line 400A filters
respectively.

† Fixing centres only See drawing P828602 or P828362 for position of cable entry hole.
