Bourns Surge Protective Devices (SPDs)
Bourns Surge Protective Devices (SPDs) offer protection for sensitive equipment against potential damage caused by lightning and electrical transient surges. These SPDs offered include AC Surge Protective Devices, DC Surge Protective Devices, Signal and Data Line Surge Protective Devices, and Coaxial Surge Protective Devices. The SPDs feature DIN-rail mounting for easy panel or cabinet integration and provide remote signalling options for monitoring. These devices operate within a temperature range from -40°C to +85°C and a minimum current rating of 20kA. Typical applications include antennas, computer networks, battery storage systems, control loops, transmitters, and instrumentation.
