This year Littelfuse introduced new surge protection modules that included the world’s first series-connected 20-kA-capable indicating surge arrestor for LED lighting applications.
The two product lines released, the LSP05 and LSP10, were designed specifically to provide transient overvoltage protection for outdoor and commercial LED lighting fixtures. The lines are constructed with thermally protected varistors and a built-in thermal disconnect function that provides additional protection from catastrophic failures and fire hazards, even under the extreme circumstances of varistor end of life or sustained overvoltage conditions.
The benefits
Lighting investments can get pretty pricey for property owners. According to Johnny Change, product manager for the LSP05 and LSP10 product lines, the modules are “designed to protect lighting fixture investments from damage due to surge events and reduce maintenance costs by providing real-time indication when the SPD module needs to be replaced.”
Applications
Real-world applications include outdoor and commercial LED lighting such as road lights, traffic lights, digital signage, service entrance lighting, parking garage lighting, flood lighting, tunnel lighting, and street lighting.
