10KV Protected LED SPD Surge Suppressors With OVP UVP Over Under Voltage Protection EN61643-11

10kV/10kA: Ideal for standard urban street lighting or areas with stable grids and low lightning frequency. It offers the best cost-to-performance ratio.20kV/20kA:Recommended for high-risk areas like highways, coastal regions, remote rural areas, or high-mast stadium lighting. Higher kA ratings mean the device can withstand more frequent and powerful surges, ensuring a longer lifespan for the entire luminaire.

We offer both versions to suit your project requirements: Parallel: Easier to install. If the SPD fails, the light stays on but is no longer protected. Series: This is the preferred choice for most professional projects. When the SPD reaches its end-of-life, it automatically disconnects power to the fixture. This ""failsafe"" mode alerts maintenance teams to replace the SPD, ensuring the expensive LED luminaire is never left unprotected."

Yes. Our SPDs are designed for harsh environments with an IP66 or IP67 rating. They are housed in flame-retardant casings and fully encapsulated with high-grade epoxy resin. This ensures reliable operation against heavy rain, high humidity, and temperature fluctuations from -40°C to +85°C.

Yes, we have dedicated Signal SPD (Signal Surge Protective Device).Ordinary power SPD for AC mains cannot be used on dimming signal wires (DALI, 0–10V, 1–10V). Power SPD has high capacitance and high clamping voltage, which leads to signal distortion, unstable dimming or loss of communication. Signal SPD is specially designed for low-voltage control lines: 0–10V, 1–10V, DALI and D4i bus cables. It protects the dimming interface of LED drivers from induced lightning surges, especially for outdoor street lights with long exposed signal cables.
