12 V vs PoE 48 V power supply

BIZ-TH100 comes in 2 variants – PoE 48 V (IEEE 802.3af) and 12 V power supply. Both variants come with their respective power adapter.

 

PoE 48 V

Advantages:

  • No need for a power adapter if the switch has PoE
  • No need for a power outlet
  • Only one Ethernet cable required

Disadvantages:

  • Heats up slightly more due to power conversion to 12 V which is the Device operating voltage

 

12 V

Advantages:

  • Less heating because the Device receives operating voltage with no conversion
  • Temperature sensor is even less affected by the components heating
  • The switch itself heats up less because it does not deliver power to the Device

Disadvantages:

  • 12 V variant needs a special, included, power adapter, a power outlet and an additional Ethernet cable
