The board has the following power supply connector:
•External Power Supply – the board can be powered through a 9-35 V DC connector on the back panel.
The back panel DC connector is compatible with a 6.4 mm/OD (outer diameter) and 2.5 mm/ID (inner
diameter) plug, where the inner contact is +9 (-5%)to +35 (+5%) V DC and the shell is GND. The
maximum current rating is 2A/12V.
Contact resistance: 30m Ohm Max. At AC 100mA Max .1KHz
Insertion force: 3.0K g Maximum.
Rated voltage and current: DC12V.2A Max
Dielectric withstanding voltage: 500V AC for 1 Minute
NOTE:
External power voltage, 9 - 35 V DC, is dependent on the type of power source used.
B.
POE
(PD
type)
From power source equipment (PSE) provided power via conventional CAT5 Ethernet cable.
PoE+ power sourcing equipment provides 50 to 57 Vdc – an increased and much tightened range
compared to 44 to 57 Vdc for PoE. Also, consider this: the current for PoE is 350mA, while the current
for PoE+ is a whopping 600mA. This provides as much as 25W at the powered device after allowing for
cable voltage drops.
