2.5 Electrical Considerations
2.5.1 Power Supply Considerations
CAUTION
The external 12-19 V DC jack is the primary power input connector of Intel NUC Board
D54250WYB and Intel NUC Board D34010WYB. However, the board also provides an
internal 1 x 2 power connector that can be used in custom-developed systems that
have an internal power supply. The internal 1 x 2 power connector is a Molex 5566-2
header which accepts a Molex 5557-02R connector from the power supply.
There is no isolation circuitry between the external 12-19 V DC jack and the internal
1 x 2 power connector. It is the system integrator’s responsibility to ensure no more
than one power supply unit is or can be attached to the board at any time and to
ensure the external 12-19 V DC jack is covered if the internal 1 x 2 power connector is
to be used. Simultaneous connection of both external and internal power supply units
could result in potential damage to the board, power supplies, or other hardware.
System power requirements will depend on actual system configurations chosen by the
integrator, as well as end user expansion preferences. It is the system integrator’s
responsibility to ensure an appropriate power budget for the system configuration is
properly assessed based on the system-level components chosen.
• The back panel input range is 12-19 V DC
• The internal power connector input range is 12-24 V DC
