1-channel surge arrester ECONOMICAL series for LAN 100Mbit, compatible with 100Base-T, PTF-51-ECO/PoE, manufacturer
1-channel LAN surge arrester, designed for surge protection of LAN devices operating in 100Mbit LAN networks, such as IP-CCTV cameras, Internet of Things, LAN switches, home and industrial automation. It is compatible with 10Base-T and 100Base-T Ethernet, using any type of cabling. Compared to previous series, care has been taken to protect against overvoltage’s in PoE circuits of any type along with the discharge of charges to the ground. High-quality printed circuits together with tuned differential pairs provide very good transmission parameters and contribute to the elimination of crosstalk that cause unstable LAN operation.
The product is intended for installations where connected LAN end devices are inside buildings and no part of the cable passes outside buildings. In the absence of the conditions or the need to increase the level of surge protection, a PRO or EXT series limiter should be used.
A special connection circuit also protects device against surges and against voltage increase on PoE power lines in any of the possible standards. Lines 4-5 and 7-8 are interconnected because LAN Base-100T uses them only to power PoE. The PTF-51 protects both groups of power pairs against an increase in voltage above 58V and damage to the power supplies of terminal devices, such as switches or IP cameras. The PoE transmitted through the protector can be up to 60W (compatible with HiPoE).
PTF-51-ECO/PoE ensures the continuity of the shield FTP cable, but in the ECO series it is not connected to the earthing.
To protect a single LAN circuit, two identical series surge arresters should be used, mounted on two ends of cable and grounded accordingly. If it is necessary to protect multiple circuits, it is recommended to use a multi-channel surge arresters on the LAN switch side and one-channel on the LAN end device side.
