PoEp minimum voltage
Lets assume current is 0.35A and calculate power delivered to the load by four pairs
| 44V | 51V |
|
|
|
Power dissipation | 3.06W | 3.06W |
on 4 pair |
|
|
|
|
|
Maximum power | 27.74W | 32.64W |
delivered to the PD |
|
|
It means, that at 51V, for the same power dissipation on the cable, power delivered to the load will be 4.9W more then at 44V.
The advantage of higher voltage is further increased for higher currents than 0.35A
