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.
Two bus bar examples for DC power connections between circuit boards. These assemblies use an edge sealed construction and employ a special insulating washer that allows compression of the two conductors onto the board while insulating the fastener from the live conductor.
PCB to PCB
Size: 0.5” x 2” | Thickness: .030” & .060” | Voltage: 48V | Current: 35A
A complete set of epoxy powder coated, color coded bus bars (for differing voltages) are stamped, brazed, machined and with hardware installed to provide power interconnects directly from the power supply in a rugged package.
Information Storage Systems
Size: 1.2” x 19” | Voltage: 48VDC | Current: 300A
Modem supercomputer systems operate at extremely low voltages, and require a high concentration of current. This two-conductor bus bar assembly is constructed from machined, stamped, and soldered components that are insulated with a high quality epoxy powder coating, then laminated together to provide a low inductance power path distributed across a large circuit board or backplane.
Supercomputer Bus bar
Size: 2” x 19” | Voltage: 3VDC | Conductors: .060” & .5” | Current: 450A
Distributing power to eight blades in a large server is easily accomplished with this two conductor laminated bus bar complete with blind mate power connectors. Short cable assemblies are built into the bus bar for system monitoring.
Size: 16” x 28” | Voltage: 48VDC | Current: 240A | Conductors: .060”
An excellent combination of value! This multi-layer, laminated bus bar incorporates several different connectors for both power and signal, and through careful engineering, a wire harness is used for signal distribution. MERSEN can engineer fully tested and serialized solutions to solve your power distribution challenge.
High End Server
Size: 5” x 9” x 17” | Voltage: 48V | Conductors: .060” | Current: 400A
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.
Computer Backplane Power Distribution
Length: 14” | Thickness: .060” | Voltage: 3VDC & 5VDC | Current: 100A
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.
Size: 12” x 9” | Thickness: .125” per layer | Voltage: 48V | Current: 250A per layer
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.
Power Distribution for Optical Systems
Size: 5” x 18” | Voltage: 48VDC | Current: 75A | Conductors: .050”
