Designed to meet the point-of-entry requirements of MIL-STD-188-125-1 & MIL-STD-188-125-2 for short and intermediate pulses, LCR’s FH1960 HEMP filters also meet high insertion loss performance for SCIF, TEMPEST and other applications.
LCR’s latest filters are capable of carrying full rated current without exceeding a 25 degree rise above ambient temperature and can be operated continuously at their rated currents and voltages while withstanding a 40% current overload for 15 minutes without degradation.
These HEMP filters comply with all applicable requirements of MIL-F-15733 latest revision and UL1283, and are fitted with high transient suppressors in front of the inductive input circuit which results in low residual currents during an EMP pulse and protects the connected equipment.
In addition, these Filter cabinets are supplied with two separate removable covers to access input and output terminals. The filtered compartment is supplied with an EMI (RF) non- corrosive, environmental gasket to prevent RF Leakage and accommodate maximum isolation between input and output compartments. For further safety, bleeder resistors are built into each filter line to discharge the capacitor voltage to ground potential during a power shutdown.
