signal protection
2.10.1 POE Outdoor Lightning Protection 6KV Protection Scheme
Solution Advantages: Designed for outdoor POE network port surge protection, this solution adopts secondary protection, ensuring reliable operation. It guarantees the signal integrity at high temperatures, meets IEC61000-4-2, Level 4 standards, with a contact discharge of 30kV and air discharge of 30kV. IEC61000-4-5 standard testing: 10/700μs, 40Ω, 6kV, ±5 times. This solution ensures that the high-temperature transmission is lossless.
Solution Advantages: After rectifying the 48V voltage, this solution uses only one high-power TVS (Transient Voltage Suppressor) LM1K58CC to protect the DC to DC converter at the output, eliminating the need for the MOV (Metal Oxide Varistor) and inductor L1 from Solution 1, saving space and cost.
