Hi,

 

I have a number of TL-POE10R devices which appear to be operating at a much lower power rating than when they were when purchased.

 

I am using them to provide power and data to a 10W single-board-computer.

 

Initially they appear to be working fine, but after several weeks, sometimes months, the TL-POE10R device seems to be incapable of outputting the full 12W needed to provide power to the board.

 

Is this a known behaviour, or is there any preventative steps we can take to stop this from happening?

TL-POE10R should only be guaranteed to provide 12V. If you have a voltmeter, you can measure the voltage.

Where does PoE come from? Are you sure it is not a problem of PoE-injector/switch?

I met a problem with poe150s, when there is not stable electricity and there is some problem with power adapter, but 10R is fully passive device, so it is strange.
