Thermally-protected surge-protection module certified to IEC/EN 61643-11

Littelfuse has introduced a new series of thermally-protected surge-protective devices that provide robust transient over-voltage protection for outdoor and commercial LED lighting fixtures. The module is capable of providing 10kV/5kA surge protection and is certified to IEC/EN 61643-11. The device's surge-handling capability enhances an LED lighting fixture’s surge immunity and extends its operating lifetime. Proprietary varistor technology guards against hazards affecting a light or a facility due to 'end-of-life' or extreme surge conditions. It is available in both parallel-connected and series-connected formats. The series connection option disconnects the power to protect the luminaire; the parallel connection disconnects itself at end-of-life and keeps the luminaire powered. Applications include roadway lighting, parking garage lighting, wash wall lighting, traffic lighting, flood lighting, digital signage, tunnel lighting, and street lighting. “The LSP05GI Series LED Lighting Surge Protection Module is suitable for use around the world because it helps luminaire manufacturers meet the latest IEC/EN 60598-1 Standard,” said Todd Phillips, global marketing manager for LED lighting, Littelfuse.
