Bus Bar for 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.

Computer Backplane Power Distribution

Epoxy powder coating allows multiple conductors, formed to differing geometries, to be assembled into a single unit. Insulated and bonded together, this assembly carries power to the backplane without adding costly and complex layers to the backplane.


Length: 14” | Thickness: .060” | Voltage: 3VDC & 5VDC | Current: 100A


Computer Backplane

Redundant power supplies plug into this laminated bus bar design, and feed high current power into the computer backplane. Note the five glass (FR-4) mounting supports, which are bonded to the structure, to create a rigid, insulated mounting system.

Power Distribution for Optical Systems

Power distribution bus bar used in Optical Network System. This efficient and compact bus bar is designed to proved 48V power onto a backplane from its power supply, through circuit protection, common and differential mode inductors, film capacitors and resistors, all without the need for a separate PCB for the soldered connections of the resistors and capacitors.


Size: 5” x 18” | Voltage: 48VDC | Current: 75A | Conductors: .050”


Cellular Base Station Power Distribution

An economical design that carries power from multiple power supplies onto the backplane within a Base Station Cabinet. Individually laminated and assembled together reducing a complex wiring scheme to a simple component, saving both space and assembly time.


Size: 7” x 7” x 19” | Voltage: 48VDC | Conductors: .060” | Current: 125


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.


Size: 12” x 18” | Voltage: 48VDC | Conductors: .090” | Current: 250A


Internet Router

This two-conductor bus bar distributes DC power within an internet router. The laminated structure utilizes tabs with offset forms and clinch hardware to mount directly onto the midplane, while allowing for proper airflow. High current pluggable connectors are mounted directly to the bus bar for interchangeable power supplies.
