PoE Power Budget Examples
Example #1
This example is for the Advantech
65 W. We will use 15 W as the maximum router power consumption; see Chapter efchap:BasicParams.
You can use this power supply to power:
• up to three PoE devices (3
• just one PoE+ device (1
Example #2
To power four PoE+ devices, you should use a power supply with a minimum rating of 135 W. You can
calculate this as follows:
• Required power supply wattage = 4
Ensure that the power supply you use can provide enough power to cover the required power con-
sumption of all connected PoE devices, including the router itself. We recommend using a power
supply with some power reserve.

15.4 W + 15 W = 61.2 W < 65 W),
30 W + 15 W = 45 W < 65 W).
30 W + 15 W = 135 W.
