Product Features
Computer room system single-phase power supply three-level lightning protection
①. Using instantaneous balanced voltage lightning protection technology, it can continue lightning protection when the grounding resistance value becomes large.
②. You can connect the original standard lightning protection ground wire. When the resistance of the local line becomes large or after the failure, the effective lightning protection continues to achieve double protection.
③ A series of lightning arrester failure protection function is installed to prevent lightning damage caused by the failure to replace the lightning arrester in time when the lightning arrester fails frequently during lightning season
Applicable industry and scope
It is suitable for single-phase 220V power supply equipment in the security industry (safe city, Xueliang project), radio and television industry, communications industry, and intelligent transportation.
