Backplane interfaces:
Power backplane connectors PCMG2.11, CONEC CPH47W23FGF3SK9X or equivalent, is the
main interface on the backplane for the power supply unit. For this backplane, two power
connectors are assembled by default and connected in layout to the Mate-N-LOK connectors for
the AC or DC input. The other two power connectors are not assembled.

ATX power backplane connectors, is an alternative power supply, using as backplane
interface connectors ATX_POWER1 and ATX_POWER2 from Molex 39-28-8200 or equivalent on
the rear side of the backplane. Note that those connectors are not assembled by default in this
backplane version.

Power input, AC or DC is made using two power MAT-N-LOK connectors,
AMP 0-0173925-1 or equivalent.
Power output is made via
o M4 power bolts; maximum current 70A/bolt:
2x M4 power bolts for +3.3V
2x M4 power bolts for +5V
4x M4 power bolts for GND
*possible further M3 power bolts or fastons assembly options for +12V, +3.3V, +5V and GND.
