Lightning Protection Device 2 Wire Signal SPD 5kA 10kV DIN Rail Mounting
LS-CS Series 2-Wire Control Signal Lightning Arrester (Full-Mode) is designed for communication equipment such as dedicated communication lines, telemetry signals, measurement and control signals, PLC analog control systems, and 4-20mA current loops. Suitable for installation in LPZ 2-3 and subsequent lightning protection zones, it provides full-mode fine protection for two signal lines.
Featuring an integrated module structure, the product supports 35mm DIN Rail mounting with through flow. The multi-level protection circuit ensures high flow rate and low residual voltage, covering both line-line and line-ground surge paths. With a line-to-line bandwidth of 3MHz, it supports high-speed signal transmission without distortion.
