Surge Protection Modules
Surge protection modules combine unparalleled packing densities, application versatility, proven reliable hybrid circuitry, simple installation and optional ‘loop disconnect’ facilities – features which make the series the ultimate surge protection solution for process equipment, I/O systems and communications networks.
Believed to include the world’s first series-connected indicating surge arrestor module, the LSP10 handles surges of up to 20,000A and can be used for outdoor LED applications.
Using Parallel Connections
Additionally, Littelfuse offers the LSP05, configured with parallel connections, also specifically to provide transient over-voltage protection for outdoor and commercial LED lighting fixtures. Constructed with the company’s thermally protected varistors, the two surge protection device modules have a built-in thermal disconnect function that provides additional protection from catastrophic failures and fire hazards, even, says the company, under the extreme circumstances of varistor end-of-life or sustained over-voltage conditions. Applications include roadway lighting, traffic lighting, digital signage, service entrance lighting, parking garage/lot lighting, flood lighting, tunnel lighting, and street lighting.
The LSP10 is available with either parallel or series connections; with the parallel-connected versions, an indicator wire can activate an LED to tell maintenance personnel when to replace the SPD in order to ensure the luminaire remains protected. The LSP10 series-connected version cuts luminaire power off to provide a clearly visible indication the SPD should be replaced.
They offer a clear indication of SPD replacement prevents future surge damage to luminaire and are sealed to IP66. They are packaged in a compact 48x48x30mm form factor which makes them easy to mount inside a luminaire; mounting tabs simplify installation and replacement.
