LED Surge Protector Limits Let-Through, Has Low Clamp Voltage

Littelfuse, Inc. has introduced a series of LED lightning surge protection modules with greater transient over-voltage protection for outdoor and commercial LED lighting fixtures. The LSP10GIHP Series Surge Protection Device (SPD) Module is reportedly 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.

Constructed with Littelfuse thermally protected varistors, this series is available in a choice of operating voltages (277 V or 480 V). The 277 V can be confidently used in 120 V and 240 V systems. The 480 V can be confidently used in 347 V systems and some 277 V systems. A built-in thermal disconnect function protects against catastrophic failures and fire hazards, even under varistor end-of-life or sustained over-voltage conditions.

Applications include roadway lighting, parking garage lighting, wash wall lighting, traffic lighting, flood lighting, digital signage, tunnel lighting and street lighting.

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