FAQ
Can the cable length of this SPD for outdoor lighting be customized?
Yes. We can customize the cable length according to your requirements, with a MOQ of 1000 pieces.
How do I choose between 10kV/10kA and 20kV/20kA protection levels?
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.
"What is the difference between Series and Parallel installation? Which is better?
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."
Is this device fully waterproof for extreme outdoor use?
Yes. Our SPDs are designed for harsh environments with an 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.
Does poor earthing render the SPD useless?
High earth resistance or loose PE connection prevents surge current from discharging.
