Product Introduction
Surge Protective Device (SPD), also known as lightning arrester, provides fast and reliable overvoltage protection for low-voltage power systems. It can quickly limit transient voltage and discharge surge current to protect sensitive electronic equipment. Our SPD products feature low residual voltage, fast response, long service life, and high safety.
Key Advantages
✅ Fast Response Speed
Response time ≤25ns, quickly clamp surge voltage
✅ High Surge Current Capacity
Max discharge current up to 100kA, strong lightning protection
✅ Low Residual Voltage
Effectively protect precision equipment from overvoltage damage
✅ Remote Fault Signal
Optional remote alarm contact for intelligent monitoring
✅ Safe & Reliable Structure
Thermal decoupling design, prevent fire and breakdown
✅ DC Models
Suitable for grid, PV, energy storage, telecom systems
