Infrastructure

Mersen laminated bus bars offer uncompromising electrical performance while minimizing EMI, RFI and crosstalk. As data volume and broadband use continue to expand, performance demands increase for high-speed servers, blade servers, network backbone equipment, engineering work stations, and such data storage systems as disk arrays.

The low-profile of a laminated bus bar provides computer equipment manufacturers with the ultimate package efficiency, ease of service, and consistent quality necessary to satisfy the most demanding customers. A properly engineered power distribution plan, including laminated bus bars, can also include thermal management, acting as a heat sink, and the bus bar’s form fitting designs help increase the air flow within a system where space is at a premium.

tc_router_backplane

Router Backplane Distribution

Two-conductor laminated bus bars designed to distribute DC power from dual power supplies across the backplane of an internet router. The insulation system uses a molded-edge seal around the perimeter as a cost effective means of providing the proper creepage distance between the two conductors while protecting the individual conductors from dust and contaminants. Due to the low voltage of the system, MERSEN engineers assured that the design has sufficient cross sectional area for a minimal voltage drop.
