The LSP05GI Series LED Lighting Surge Protection Module is capable of providing 10kV/5kA surge protection and is certified to IEC/EN 61643-11. The surge handling capability enhances an LED lighting fixture’s surge immunity and extends its operating lifetime.

The thermally protected 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 the power systems of 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 at Littelfuse.

The IEC 61643-11 and EN61643-11 certification of these modules allow luminaire manufacturers to meet IEC/EN 60598-1, the international testing standard for luminaires, as well as UL 1449, while the double-insulated cable wire makes them suitable for use in luminaires designed for Class I and Class II installations. A built-in LED indicator also alerts maintenance personnel to the need for replacement and it is available with either series connections or parallel connections with operating voltages ranging from 120V to 480V.

The LSP05GI Series is available in bulk in minimum order quantities of 80 pieces.
