PS1240 and PS1241 6Ux16HP cPCI

Technical Details

The PS1240 is a 6.5U (or 6U) tall, 16HP wide power backplane, intended for use with the PS1300 or PS1400 series of modular CompactPCI backplanes, or in any other application where large supply currents are required. The PS1240 will accept up to two Positronic type 500W power supplies operating in current sharing mode. Any power supply that is compatible with the backplane dimensions and pinout shown below may be used. Either AC or DC power is supplied to the powerplane by means of a six contact Mate-n-Lok connector.

There are 5 ATX-style power connectors on this power plane, for distribution of regulated power to the modular CompactPCI backplanes. The connectors used are Molex “Mini-Fit Jr.” series headers or compatible connectors. These are the same connectors that are recommended for ATX style PC power supplies.

The CompactPCI backplanes will be connected to the power backplanes by means of cable assemblies with mating “Mini-Fit Jr.” receptacles at either end. The PS1240 also has several rows of power taps for use when large supply currents are required, or ATX connectors cannot be used (the PS1241 is simply a partially populated version of the PS1240).

One power backplane can supply power to one or more CompactPCI backplanes, subject to the current requirements the CompactPCI backplanes.
