Electromagnetic Compatibility (EMC)
A metal oxide VDR (depending upon converter model)
together with an input fuse and an input filter form an effective
protection against high input transient voltages, which typically
occur in most installations, but especially in battery-driven
mobile applications. The H series has been successfully tested
to the following specifications:
