Telecommunications

In the intensely competitive telecommunications market, manufacturers of equipment for Cellular Base Stations and Internet Routers must offer their customers exceptional performance and dependability. With their consistent quality, excellent electrical characteristics, and minimal EMI, RFI and crosstalk, Eldre laminated bus bars provide the perfect solution.
Eldre laminated bus bars offer telecommunications equipment manufacturers many other advantages as well, including ease of assembly, superior thermal management, reduced weight, packaging efficiency, and overall cost-effectiveness over alternative means of power distribution.
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.

Cellular Base Station Power Distribution

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

Size: 12” x 18” | Voltage: +5V, -5V | Current: 110A
Redundant Power Input

When system requirements call for redundant power supplies, laminated bus bars are ideal. This two-layer design utilizes press-fit sockets for power supply input, and mates downstream with a custom power distribution network.

Redundant Power Input

Size: 3.5” x 8” | Voltage: 48VDC | Conductors: .125” | Current: 50A
Backplane Power Distribution

Sixteen layer laminated bus bar distributes +48V and Return across a back plane in a rack system for a network routing application. Heavy gauge clinch hardware and anti-rotation tabs accommodate cable connections. The entire assembly is hermetically sealed using epoxy edge fill.

Size: 1” x 18” | Voltage: 48VDC | Conductors: .032” | Current: 75A per layer
Telecommunications Board Level Power Distribution

When board space is at a premium, laminated bus bars provide the perfect space saving solution. The bus bar is designed to be soldered into a PCB, and includes an integrated compliant pin connector, which allows for interchangeability of either the power supply or PCB.

Telecommunications Board Level Power Distribution

Size: 0.6” x 10” | Voltage: 60VDC | Conductors: .050” | Current: 80A
internet bus bar system

U-shaped, with angled power input tabs, feeding around a rack mounted frame. The unit also has plated, soldered bushings for bullet-style circuit breakers.

Internet Bus Bar System

Size: 5” x 9” x 17” | Voltage: 48V | Conductor thickness: .060” | Current: 400A
circuit breaker bus bar

This seven conductor, nickel-plated assembly receives filtered input power, routed through pluggable breakers, and directed to output terminals within a rack-mounted system. Such compact routing offers improved packaging and improved air flow – both key benefits of laminated bus bars.

Circuit Breaker Bus Bar

Size: 3” x 6” | Voltage: 48VDC | Conductor thickness: .060” | Current: 75A
Telecom Power Distribution

Part of a rack mounted circuit breaker network, this three-conductor, single-layer laminated bus bar assembly is used to provide power connections to a group of circuit breakers. Power connections are made at each end, and three banks of Faston® tabs provide A, B, and Ground connections for twenty circuit breakers.

Size: 10” x 3” x 3″ | Voltage: 48VDC | Conductor thickness: .125” | Current: 480A
Filtered Power Input Bus Bar

A two-conductor bus bar routing filtered DC power through ring lugs and clinch hardware, terminating in multiple power connectors mounted in a 1U rack-mounted power drawer.

Filtered Power Input Bus Bar

Size: 1.5” x 9” | Voltage: 48VDC | Conductor thickness: .050” | Current: 200A
Backplane Power Distribution

Three-phase shielded power is fed from a single power supply, extending horizontally along a backplane. Eleven sets of gold-plated pins engineered to pass directly through the backplane, ensuring high reliability and low contact resistance connections to individual boards.

Backplane Power Distribution

Size: 7” x 18” | Voltage: 12V | Conductor thickness: .040” | Current: 48VDC
Internet Router Backplane Bus Bar

Three power supplies feed this DC bus bar assembly through a repeating series of blade style pluggable output “tabs” along its length. The long, narrow design makes short jump connections clean and easy for board mounted pluggable connectors. The manufacturer benefits from the efficient, low profile design, and clean distributed capacitance that are the natural results of laminated bus bars.
