Data and telecommunication line surge protector SFLM-H

for lightingfor railway applicationsfast response time

SFLM-H data transmission channel surge protector is designed in accordance with relevant railway standards and meets the requirements of TB/T2311-2017. It is used for lightning protection of data transmission channel signals, measurement and control systems; It’s also applied to lightning protection for data transmission lines of electronic measurement and control system of two-wire floating ground that needs protection, such as TTY \RS422\RS485, railway LEU active transponders, axle counting sensor lines, protecting subsequent systems and equipment against overvoltage and overcurrent damages caused by lightning and industrial interference. • Builtin two-level overvoltage protection, coarse protection and fine protection; • Large flow capacity, low residual voltage; • Fast response time; • AC and DC signal control line protection
