MPE HEMP Prot Control Line A

DESCRIPTION

Ranges of multi-line HEMP protection filters for control lines suitable for use in various HEMP protected installations. All lines are individually filtered and feature inductive input to offer both good continuous wave EMC performance and superior transient handling performance. All lines feature high-energy varistor transient suppressors at the input end. Two ac ranges of filters are offered rated at 250VAC and 120VAC meeting the pci requirements of MIL-STD -188-125-1 & -2 for high voltage control lines working at >90V. A third range rated at 28VDC, meets the pci requirements of MIL-STD -188-125-1 & -2 for low voltage control lines working at <90V

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
EN60950/IEC60950
UFGS 13.49.20.01
USACE 13.27.54.01

 

FEATURES

  • Ranges for high and low voltage control lines (250VAC, 120VAC, & 28VDC)
  • 1A current rating
  • Individually filtered lines
