LSP05 and LSP10 surge protection modules from Littelfuse protect luminaires, save money

Image of Littelfuse's LSP Series LED Thermally Protected Surge Protective DeviceThe LSP05 and LSP10 Surge Protection Modules from Littelfuse provide transient overvoltage protection for outdoor and commercial LED lighting fixtures. They provide robust surge current handling capability. The close proximity of the integrated thermal element to the Varistor body ensures quick response to lightning-induced surges or nearby load switching. Applications include outdoor and commercial LED lighting, including roadway and traffic lighting, digital signage, and service entrance, parking garage/lot, flood, tunnel, and street lighting.

LED Lighting Design Guide
