The SD Series are user-friendly devices for protecting electronic equipment and systems against surges on signal and I/O cabling. The exceptionally high packing densities are the result of an ultra slim footprint for individual modules, which can double-up as feedback terminals. Each module provides full hybrid surge protection for 2 and 3-wire loop protection.
