SPD-20HP-480S

SPD-20HP Series Description: The MEAN WELL SPD-20HP Thermally Protected Surge Protective Device delivers reliable transient overvoltage protection, specifically designed for outdoor and commercial LED lighting fixtures. This self-protecting device is built with thermally protected varistor technology, ensuring superior performance and safety. Equipped with a built-in thermal disconnect function, it provides enhanced protection against catastrophic failure and fire hazards, even under extreme conditions such as varistor end-of-life or sustained overvoltage events. The SPD-20HP stands out by offering coordinated surge protection with more LED drivers than standard SPDs, thanks to its exceptionally low Measured Limiting Voltage (MLV) and Voltage Protection Level. This lower clamping voltage not only safeguards sensitive components but also helps extend the luminaire’s lifespan. For added convenience, an integrated LED indicator alerts users when module replacement is required, ensuring consistent performance and peace of mind.
