Устройство защиты от перенапряжения Ewimar PTF-51-ENG/PoE/Micro LAN для IP-камер

PTF-51-ENG/PoE/Micro – Miniature LAN surge protector for IP cameras The PTF-51-ENG/PoE/Micro surge arrester is a modern solution that effectively protects LAN networks, especially in the context of IP cameras. Due to its small size, this device is ideal for locations where grounding is not possible, eliminating electromagnetic pulses that can threaten the stability and security of monitoring systems. Protection against surges and lightning discharges The PTF-51-ENG/PoE/Micro provides advanced protection against surges and lightning discharges. With individual protection for each transmission pair, the device effectively protects outdoor cameras and other LAN end devices from damage caused by sudden voltage spikes. Compatibility with 10-BaseT and 100-BaseT LAN networks The arrester is fully compatible with 10-BaseT and 100-BaseT LAN networks, making it a versatile solution for various installations. It works with category 5 and 6 UTP cables, ensuring flexibility in cabling selection. MOSFET technology for improved efficiency The use of MOSFET technology in the PTF-51-ENG/PoE/Micro increases the efficiency of surge elimination and reduces the risk of damage. The device protects against voltage increases on PoE power lines above 58V, which is compliant with various power transmission standards, ensuring reliable and safe operation. Application in IP industrial cameras The PTF-51-ENG/PoE/Micro arrester is an ideal solution for monitoring systems, including IP industrial cameras. Due to its design, the device can be easily connected and hidden in enclosures, making it a practical choice for both indoor and outdoor installations (in an additional IP66 enclosure).
