Application for Ethernet
- What are the advantages of the GDT+TVS type surge protection? It provides a two-step surge protection mode: the first-stage GDT protection, releasing strong surge intrusion and reduce the strength of the surge; it is followed up the second-stage TVS fine protection, achieving a lower residual voltage value.
- If the wires on the line side and the equipment side are connected reversely, will it affect surge protection? When the wire is connected reversely, TVS becomes pre-stage protection, and GDT is post-stage protection. The nominal discharge current of TVS protection will be much lower than GDT. If it encounters a surge intrusion, it may cause damage to the TVS. The second-stage GDT protection will also play a role in surge protection, but the residual voltage value will increase, which is a risk to the protected equipment.
- The PE/GND of WTH-SG/RJ45 has two terminals, what’s the use of a GDT connected in series between the two terminals? When the local grid voltage unstable and there’s signal interference, it is recommended to ground the terminal on the left side. If an additional 90V GDT is connected in series, the surge discharge voltage value can be increased by 90V, effectively blocking the interference of unstable ground voltage.
- How do I determine the quantity of surge protector that I need for protecting the equipment? Surge on the STP cable will be transmitted in two directions to the ends of the cable. The surge protector A protects the equipment on the A side, such as an ethernet switch, etc. And Surge protector B protects the equipment on the B side. such as an ethernet equipment. If only the device on one end of cable needs to be protected, then only one surge protector is needed.
Application for PoE
- What are the advantages of 1-2, 3-6, 4-5, 7-8 line full protection mode of GDT+TVS type surge protection? If you don't know whether the system is 100M or 1000M, which PoE structure or wiring mode the system is, the full line surge protection mode of GDT+TVS avoids the confusion of your selection.
- What is the role of GDT connected in series between 5-8 lines? 4-5 and 7-8 PoE lines, on the basis of common mode (line-ground) surge protection, add additional differential mode (line-line) surge protection, providing more refined protection.
