The SPD 10S 277 thermally-protected surge protection device from Mean Well is a self-protected device which is specially-designed to be used in outdoor and commercial LED lighting fixtures for transient overvoltage protection.
Anticipated applications include outdoor and commercial LED Lighting, roadway lighting, traffic lighting, digital signage, wall wash lighting, parking garage/lot lighting, flood lighting, tunnel lighting, street lighting, and so on.
The SPD 10S 277 is constructed with thermally protected varistor technology. Its built-in thermal disconnect function provides additional protection to prevent catastrophic failure and fire hazard even under the extreme circumstances of varistor end-of-life or sustaining over voltage conditions. It also features a built-in LED indicator that notifies when replacement of the module is needed.
