Littelfuse Introduces New LSP05GI Series Thermal Protection SPD: 10kV/5kA Surge Protection Module

Littelfuse introduces a new line of thermal protection surge protection devices that provide powerful transient overvoltage protection for outdoor and commercial LED lighting. The LSP05GI series of LED lighting surge protection modules are capable of providing 10kV/5kA surge protection and are IEC/EN61643-11 certified. Its surge handling capability enhances the surge immunity of LED lighting fixtures and extends their working life.

Littelfuse thermal protection varistor technology protects fixtures or installations from "end of life" or extreme surge conditions. Parallel and series models are available. The series model protects the luminaire by disconnecting the power supply; the parallel model disconnects at the end of its life and continues to power the luminaire.

Applications include road lighting, parking lot lighting, wall washing, traffic lighting, floodlighting, digital signage, tunnel lighting and street lighting.

“The LSP05GI series of LED lighting surge protection modules can be used around the world as it helps luminaire manufacturers meet the latest IEC/EN60598-1 standards,” said Todd Phillips, global marketing manager for Littelfuse LED Lighting.

The LSP05GI series of LED lighting surge protection modules have the following key advantages:

These modules are certified to IEC61643-11 and EN61643-11 to help luminaire manufacturers meet the international luminaire test standard IEC/EN60598-1;

Double insulated wires make it suitable for luminaires designed for Class I and Class II installations;

Built-in LED indicators notify maintenance personnel when a replacement is required.
