This product line is designed to provide protec-
tion against induced AC power current, direct
power contact and the natural lightning strike.
The HVR250 product line is widely used in the
fi
eld of telecommunications and network-
ing, ISDN and XSDN equipment. It also helps
equipment manufacturers pass ITU K20, K21 and
telcordia requirements.
