Cooper Bussmann Surge Protective Device for BNC Coaxial Data Cables


Welcome to G-TV! Today I will be showing Cooper
Bussmann’s surge protective devices for BNC coaxial data cables. SPDs for coaxial
connections are two stage in-line surge arrestors used for protecting coaxial cable systems
such as video and camera systems from potential damage. These connectors are available in
three models. The BSPD5BNCDD for direct shield connection or VCD, the BSPD5BNCDI for indirect
shield connection or VCID. Both of these surge arrestors are mounted on a 35mm din rail or
on a supplied rail terminal lug. They’re connector terminated data or video signal
cables are plugged into the sure arrester with the equipment plugged into the protected
side. They have a nominal voltage of 5 volts DC with a max continuous voltage of 6.4 volts
DC. The third model here is the BSPD5BNCSI. This shielded surge arrestor is directly plugged
into coaxial terminal equipment or connections, via an 18 gage outgoing earth conductor. The
input is used as a socket and the protected output is used as a plug. It has a nominal
voltage of 5 volts DC with a max continuous voltage of 8 volts DC. For both the CDI and
CSI models, the cable shield is indirectly grounded via a gas discharge tube to avoid
leakage pickups. All three models are IP20 projected, UL497B approved, and meet IEC 61643-21 standards. SPD’s for BNC connectors are RoHs compliant and come with a 5 year warranty.
