Миниатюрный ограничитель перенапряжения Ewimar PTF-51-ECO/POE/MICRO для защиты сети LAN

PTF-51-ECO/PoE/Micro is a miniature surge arrester that effectively protects 100-BaseT LAN networks and end devices, such as IP cameras, against the effects of surges and lightning discharges. The miniature dimensions of 56 x 31 x 27.5 mm allow for easy installation in small enclosures, saving space in installations. Protection against surges above 3.5V for each transmission pair ensures the safety and longevity of connected devices. The built-in cable with an RJ-45 plug simplifies installation, eliminating the need for additional cables and connectors. A protection level of 1kV/μs for line-ground and line-line guarantees high effectiveness in the event of lightning discharges. Compatibility with category 5, 5e, and 6 cabling allows the arrester to be used in various existing network installations. The operating temperature range from -30ºC to 60ºC allows the arrester to be used in various environmental conditions, both indoors and in an additional outdoor enclosure. PTF-51-ECO/POE/MICRO* – Miniature surge arrester for LAN network protection The PTF-51-ECO/PoE/Micro v2 surge arrester is an effective solution for protecting 100-BaseT LAN networks. Compact design and easy installation Thanks to its compact design, the PTF-51-ECO/PoE/Micro* can be easily installed in various locations, making it an ideal choice for indoor applications. Its small dimensions allow for discreet placement of the device in limited space, which is particularly important in modern installations. Protection against surges and lightning discharges The arrester effectively protects against the effects of surges, lightning discharges, and acts of vandalism. Each transmission pair is individually protected, eliminating surges above 3.5V. Version 2 was created to enhance the level of protection and improve mechanical properties, ensuring reliability in demanding conditions. Special connection circuits for PoE power The PTF-51-ECO/PoE/Micro* arrester supports PoE standards, and thanks to special connection circuits, the device ensures stable power supply and protection for devices using PoE technology.
