DC PEM Specifications
The PEMs provide –48 VDC power, which is distributed through the filter module to the dial shelf
backplane. The analog isolators in the filter module are provided with 15 VDC. The PEMs suffer no
damage if any or all outputs have no load (no load occurs when there are no cards plugged into the
backplane) or if the maximum input voltage is exceeded; however, input voltages that exceed 75 V
eventually trip the PEM 60 A circuit breaker, and you might have to reset the breaker as needed.
Table A-8 lists DC output voltage and current specifications.
