The LPXT Series Din-Rail DC surge suppressors are modular, high-speed, high-current, solid-state devices designed to protect electronic equipment and systems from transient overvoltage. The suppressor limits the magnitude of transient overvoltage that may occur on low voltage DC power lines, 4-20mA current loops or low frequency data lines. Data lines that benefit from LPXT suppression include: Ethernet,RS-485/232, Profibus, Foundation Fieldbus, DH+ or DeviceNet.The LPXT Series surge suppressors utilize only silicon avalanche suppression diodes (SASD). The suppressor provides continuous, bipolar protection and automatically resets after a surge event with no degradation to its protection capabilities. The suppressor includes a removable module with a base that mounts on a standard 35mm DIN (EN5022) rail. The suppressor size and form factor allows for convenient replacement of existing terminal blocks. The suppressor connects in a series (pass-through) configuration, the screw terminals accept two wire pairs (28 - 12AWG), and the device is rated for up to 10A of continuous current. Note: The LPXT surge suppressor REQUIRES that the DIN-Rail have a solid low impedance path to Earth ground for proper suppressor operation
