The design concept for this project was to create a rugged, lightweight power distribution system for a production lighting application. Due to the predictable performance characteristics of the solid copper conductors used in laminated bus bars (instead of the bulk and uncertainty of wires), the creativity of design team was tapped. Total success was achieved through compact packaging, light weight, and simplified asembly.

A series of small power supplies parallel to provide system power in a 19” rack application. Input connectors are press-fit into both the bus bar and PCBs for system simplicity. Attached to this bus bar’s right side is its mate, a 60” long vertical bus bar with pluggable output connectors for system distribution. Along the top section, signal output reports system intelligence to monitor each power supply’s performance.

Created as a total power distribution scheme, Eldre engineers worked with the client to create a bus bar structure that accepts input power and ground, divides the power through 15 circuit breakers, and routes the various currents to modular output connections. Eldre laminated bus bars can be engineered to be made with an infinite number of connectors, fuses, capacitors, resistor networks, filters surge protectors and circuit breakers. Our complete value-added assemblies are supplied fully tested and ready for installation. Manufacturing benefits by reduced assembly and test time, purchasing benefits by keeping track of fewer items and managing a reduced inventory.

Eldre engineers work closely with customers to design complete rack mounted power distribution assemblies. This PDA contains a J-shaped, four-layer laminated bus bar, three input filters, six circuit breakers, sense monitoring and dual voltage switches. Tested, serialized, and completely labeled, each PDA is ready for system installation by the customer.
