POE Power over Ethernet surge protection

Mmepe nke teknụzụ Power over Ethernet (POE) siri ike. Mmepe nke nkà na ụzụ a nwere ike ime ka ntinye na ntinye nke ngwa eletrik dị mfe, si otú a na-ewepụ mkpa maka eriri nnyefe nke onwe. N'oge a, a na-eji teknụzụ ọkọnọ ike (POE) eme ihe na sistemụ mmepụta ihe dị ka nchekwa, nkwurịta okwu, na grids smart iji nweta data, nnyefe vidiyo, njikwa mmiri, na inye ọkụ site na bọs n'ime sistemụ.
