Commercial HEMP Equipment Filter

Please enter your email address below to download.

DESCRIPTION

A 10A HEMP equipment filter meeting the pci requirements of IEC61000-4-24 pulses for severity levels 1 and 2. Both lines feature individual inductive input to offer good continuous wave EMC performance and superior transient handling performance even on supplies with low source impedance. The filter includes HEMP and EMC filtering components thus reducing the need for a seperate EMC input filter for the equipment. This filter is primarily designed to protect individual items of equipment against the E1 pulse as part of a staged protection system as described within the MPE commercial HEMP protection filters brochure.
