Hi ya all
There is an exciting new technology emerging called PoH (power over HD Base T) intended to deliver 200W (DC- up to 60V) using Cat5, Cat6 cables. One of the main applications will be powering TV screens. Now the screens can be very flat and powered by only one Cat5 cable which caries power data to the screen. A big challenge here is that we are not in power limited circuit anymore, as it is with PoE circuits. Your opinion about the following will be appreciated: 1) Cat5 cables – are they allowed to carry 1 A ? (they are typically 24AWG and rated 0.577A) 2) Are you/we going to require same insulation requirements as in PoE ? (1500V) 3) Are we talking SELV, TNV1 or we have a new definition we need to look for compliance? (such as taking 60950-21 into consideration ) Ilan Cohen, - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
