4.1.1.5 Power Supply Connectors

NOTE External power voltage, 12-24 (±5%) V DC

†

, is dependent on the type of power

supply used. 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.

CAUTION

There is no isolation circuitry between the external DC jack and the internal 2 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 DC jack is covered if the internal 2

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.

The board has the following power supply connectors:

• External Power Supply – the board can be powered through a 12-24 V DC

†

connector on the

back panel. The back-panel DC connector is compatible with a 5.5 mm/OD (outer diameter)

and 2.5 mm/ID (inner diameter) plug, where the inner contact is +12-24 V DC and the shell is

GND. The maximum current rating is 10 A.

• Internal Power Supply – the board can alternatively be powered via the internal 12-24 V DC

†

2 x 2 power connector, where pins 1 and 2 are +12-24 V DC

†

and pins 3 and 4 are GND. The

maximum current rating is 10 A (5A per pins 1 and 2).

The connector used is Molex Micro-Fit (3mm pitch), right-angled, 4-pos/dual row (2x2).

†

“Lite” SKUs support an input voltage range of 12-19V DC
