Surge protector for railway applications SFLM-C

explosion-proofbuilt-in

SFLM-C analog and digital surge protector s suitable for railway system, it'sapplied to lightning protection of analog and digital signal, measurement andcontrol system. Installed at the signal wiring board and combined with lightningprotection wiring cabinet, it performs lightning protection for each analog anddigital signal transmission line, protects the subsequent system and itsequipment against overvoltage and overcurrent damage caused by lightningand industrial interference. ● The module mainly has the functions of surge absorption, potential clamping, and ground leakage. ● Built-in two levels of coarse protection and fine protection, large flow capacity, low residual voltage. ● The module is directly inserted into the module base of the distribution board terminal, and the lightning protection components and the transmission cable realize zero-distance connection, and the protection effect is good. ● The module can be plugged or replaced when powered, without any impact on the circuit. Installation is convenient. ● The module coating is made of high temperature resistant, aging resistant, explosion-proof and flame-retardant materials. ● The module is equipped with test points, which can test all the internal components of the module separately. ●Different models have different discriminator pins to prevent incorrect insertion.
