Bustronic Rolls Out Power Interface Boards with Two Power Supplies

7/2/2003 - Bustronic Corporation, an industry leading designer and manufacturer of high performance backplanes, is expanding its line of Power Interface Boards (PIBs). The new 3U version has capabilities to support two 47-pin power supplies and has several special features.

Bustronic's standard backplane lines utilize power taps and power studs, which are wired to the power supplies. With the PIBs, Bustronic customers will be able to choose between Bustronic's standard power interface and pluggable modules. The new 3U version has two connectors for 47-pin hot pluggable power supplies meeting the PICMG 2.11 specification. Also included are power taps for +5V, 3.3V, and GND and fast-ons for +12V and -12V.

The PIB interfaces to the backplane via power bugs with 6/32 screws and includes mounting holes to be securely fixed to the chassis. Other features include a header for voltage sense and IPMB (Intelligent Platform Management Bus) interface, an auxiliary/disk drive connector, and a power switch header. The sense lines help the power supply better regulate the power at the load end. The current share lines allow multiple power supplies to share current, either on one PIB or between multiple PIBs. The IPMB interface is compliant to system management specification PICMG 2.9 Rev. 1.0. The Geographical Addressing on the power supply connector is selectable.

Bustronic also offers 3U PIBs with one power supply connector and 6U versions will be available soon.
