Application Background
Climate warming leads to an increase in thunderstorms
POE power supply and signal coexist, thus increasing the difficulty of protection
Scheme description and precautions
This scheme adopts GDT to perform common mode (eight wire) surge protection at the front end of the transformer
The rear stage of the network transformer uses TVS1 with small volume and low junction capacitance to absorb differential mode energy, TV5 has fast response time, and also has electrostatic protection function
This POE port solution complies with the 802.11 electrical standard
This POE port solution meets surge testing standards such as IEC61000-4-5 and GB/T17626.5
This POE port solution meets static electricity testing standards such as IEC61000-4-2 and GB/T17626.2
Can pass surge tests of 10/700 μ S-5/320 μ S and 1.2/50 μ S-8/20 μ 5
