Littelfuse introduces new LED lightning surge protection modules

September 19, 2016

Littelfuse Inc, a provider of circuit protection, has introduced a new series of LED lightning surge protection modules with greater transient overvoltage protection for outdoor and commercial LED lighting fixtures. The company said the LSP10GIHP Series Surge Protection Device Module is the only series-connected SPD module on the market that combines low surge let-through (measured limiting voltage or MLV) and low clamping voltage ratings with a built-in LED indicator that alerts maintenance personnel to the need for replacement. This low MLV rating helps protect a luminaire's LED driver against surge-induced failures and extends its operating lifetime, according to a company press release.

Constructed with Littelfuse thermally protected varistors, this series is available in a choice of 277 or 480 operating voltages. The 277V can be used in 120V and 240V systems, and the 480V can be used in 347V systems and some 277V systems. A built-in thermal disconnect function protects against catastrophic failures and fire hazards, even under varistor end-of-life or sustained overvoltage conditions, the release said. Applications include roadway lighting, parking garage lighting, wash wall lighting, traffic lighting, flood lighting, digital signage, tunnel lighting and street lighting.

"The LSP10GIHP Series offers the highest level of protection from transient surge voltage in the lighting market today," said Todd Phillips, global marketing manager for Littelfuse. "Its low surge let-through ensures the SPD module is compatible with the LED driver it's intended to protect, giving luminaire designers the flexibility to choose the brand and wattage of driver they want without worrying about whether it will coordinate properly with the SPD module."

The LSP10GIHP Series is available in bulk pack. Sample requests can be placed through authorized Littelfuse distributors.
