How much power can be dissipated in a single 3U PXI slot?
A. The PXI standard (Version 2.1 Section 3.7.1) recommends a maximum of 25 Watts for a 3U single slot (50 Watts for a 6U module). Pickering Interfaces chassis have been tested to 50 Watts for a single slot. It should be noted that the filler panels must be in place for unused slots in order to ensure that the forced air cooling works effectively under high thermal load conditions, as stated in the standard.
