How Surge Protection Devices (SPDs) Work
Features:
- Compact and easy to install
- MOV + GDT hybrid protection
- AC/DC compatible (Type 2 + 3)
- Surge capacity up to 15 kA
- LED status indicator
- IEC 61643 / UL 1449 certified
Benefits:
- Protects LED drivers from surges
- Extends fixture lifespan
- Reduces maintenance costs
- Reliable for indoor & outdoor lighting
A Surge Protection Device (SPD) acts as a safety barrier that protects electrical and electronic systems from transient overvoltages caused by lightning strikes, switching surges, or unstable power grids. When a sudden voltage spike occurs, the SPD instantly redirects excess current to the ground through MOV (Metal Oxide Varistor), GDT (Gas Discharge Tube), or TVS diode components, preventing damage to sensitive circuits and critical equipment.
Application Scenarios:
- LED Lighting Systems: Protects LED drivers, luminaires, and outdoor façade lighting from surge-induced failure, ensuring longer operational life.
- Photovoltaic (PV) Systems: Safeguards DC strings, combiner boxes, and solar inverters, maintaining stable energy output and reducing maintenance costs.
- Industrial Power Networks: Stabilizes voltage across AC and 3-phase power distribution systems, minimizing downtime and equipment failure.
By integrating Type 2 and Type 3 surge protection devices, and using MOV + GDT hybrid SPD technology, these protectors provide:
- Fast response to voltage spikes
- Low residual voltage for safe AC/DC operation
- Long-term reliability for lighting, solar, and industrial infrastructure
For detailed guidelines on SPD selection and application, refer to the Electrical Engineering Portal or IEC 61643-11 standard documentation.
