Power Supply Surge Protection
for Cathodic Protection Systems
ADDITIONAL PROTECTION FOR BN/HT SERIES CATHODIC POWER SUPPLIES
The Additional Protection Box, model BP12A, is an external accessory, designed for the BN/HT series cathodic protection power supplies, with nominal output currents up to 12A.
Its protection function from overvoltage discharges, up to 75KA on the system side and 40KA on the network side, is therefore added, when required, to the protection devices (varistors and 10KA gas dischargers) already present in each power supply, significantly reducing the possibility of breakage or serious damage to the power supply's electronic boards, due to external overvoltages (e.g. indirect/direct lightning strikes).
The device, assembled in a sturdy and compact metal box, is designed for easy installation in the system's electrical panel and/or inside the protection cabinet, intended to house the cathodic power supply.
