Data and telecommunication line surge protector SFLM-H/4

for lightingfor railway applicationsfast response time

The SFLM-H/4 data transmission channel surge protector is designed in accordance with relevant railway standards and meets the requirements of the TB/T2311-2017 standard. It is applied to the lightning protection of the data transmission channel signal and the measurement and control system. It’s also applied to lightning protection for data transmission lines of electronic measurement and control system of four-wire floating ground that needs protection, such as TTY \RS422\RS485 and 2B+D lines, protecting the subsequent system and equipment against overvoltage and overcurrent damages caused by lightning and industrial interference. • Built-in 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.
