The rough and rugged world of the industrial environment demands a constant and consistent supply of quality products delivered right to the production floor. Eldre’s industrial bus bar design solutions continue to deliver the ultimate in optimized, laminated bus bars to countless manufacturers of motor drives, fork lift trucks, welding machines, power generators, industrial testing machines, and more.
Eldre’s laminated bus bar designs also provide application specific characteristics, achieving a consistent level of performance that cannot be matched through wires, cables or simple bars of copper.
Mounted inside a circuit breaker power tray, individual bus bars are nested in a machined FR-4 frame to provide output connections. This assembly assures proper safety separation as well as single component installation.
Rack Mount Power Distribution
Size: 6” x 12” | Voltage: 48V | Current: 280A | Conductors: .125”
This space-saving design incorporates five conductors in two layers with clinch hardware at each end. Its laminated, edge-sealed construction is formed to stay out of the way within a tightly packaged medical testing device.
Size: 7” x 8” | Voltages: 3.3V, 5V, 12V | Current: 75A | Conductors: .040”
This three-layer bus bar is laminated with a mold-sealed construction and has nine “crown clip” power connectors that distribute power from the power supply onto the backplane. Glass mounting supports are bonded to the structure creating a rigid installation.
Motor Armature Bus Bar
Size: 20” diameter | Conductor: .125” | Voltage: 48V | Current: 250A per layer
Six-conductor, laminated bus bar assembly combines DC and AC bus bars, as well as a fuse link, all in one compact package. The system is designed to fit perfectly in a limited space and provides power to a variable speed motor in a rugged industrial environment.
Fork Lift Truck Bus Bar
Size: 7” x 7” | Current: 150A | Voltage: 42V | Conductors: .060”
This unique laminated IGBT bus bar delivers low-inductance DC power within a confined area. The design also includes six separate bus bars arranged as AC output with in-line diode connections.
Compact IGBT Bus Bar
Size: 4” x 19” | Conductors: .050” | Volts: 600VDC/150VAC | Current: .120A (DC)/220A (AC)
An excellent layout containing two large DC bus bars, along with the three AC output bus bars laminated directly on top making a complete laminated power distribution system all under a single part number. Note the inclusion of Faston® tabs for current sensing and press-fit studs for balancing resistors.
Frequency Inverter Bus Bar
Size: 13” x 18” | Current: 820A | Voltage: 550VDC | Conductors: .060” & .125”
This simple, yet complex design incorporates DC and AC bus bars, plus accommodations for three current sensors at the AC output points, all built into a flexible, geometric package designed to fit into a tight, confined operating area.
Variable Frequency Drive
Size: 10” x 15” | Current: 100A | Voltage: 550VDC | Conductors: .040” & .060”
Uniquely designed two-layer, 18 conductor, PCB-style bus bar saves valuable board space while delivering low-impedance power to power-semiconductors in automotive sound systems. All conductors are made of .025” copper, plated for solderability and the entire assembly is formed at a right angle.
Premium Audio / PCB Bus Bar
Size: 2” x 10” | Conductors: .025” | Voltage: 12VDC | Current: 6A to 16A
