Elma Electronic Inc. has introduced a 3U OpenVPX 2-slot backplane with a VPX power and ground slot as well as one VITA 62 power supply slot for development and deployment of systems that require a VITA 62 power supply. The rugged backplane can be used in a range of harsh environments in embedded applications, including custom systems.

The backplane features a VITA 46/65-compliant pass-through power and ground slot that can be SOSA aligned. The rear I/O of the VITA46/65 slot can be used for a rear transition module (RTM) or for cabling.
The backplane is designed with power studs, used for both input and output power, to act as a power source to other connected backplanes in the same chassis. The board also comes with a header for various I/O signals, including voltage sense, current share and IPMB interface as well as inhibit, enable and fail.
In addition to the assigned pins for 3.3-V, 5-V and 12-V power, all remaining pins are user-defined. The fully populated rear connectors are accessible via Elma’s slot-to-slot or slot-to-I/O bulkhead cable assemblies. The backplane comes with utility and ground planes defined.
The new board features selectable geographical addressing via a DIP switch as well as a 12-layer design to IPC Class 3, with 1-oz. copper outer layers and 2-oz. copper inner layers. With insulators or fins as a custom assembly, the backplane can be used for 270-VDC operation at high altitudes.
