SPD

The innovative value of High-Performance SPD is reflected in its intelligent protection system:

Multi-level energy coordination technology: the original "first channeling and then clamping" protection strategy, the first level uses an inert gas gap to quickly discharge direct lightning (Iimp≥50kA), the second level uses a thermal fuse varistor to accurately limit the voltage (Up≤1.2kV), and the third level TVS diode provides final equipment protection (response speed reaches picoseconds)

Status visualization system: equipped with 7-color LED life indicator and wireless remote signaling contacts, real-time display of module degradation, and uploads data such as the number of lightning strikes and leakage current to the cloud platform through 4G/NB-IoT

Safety disengagement mechanism: when the protection element fails, the patented mechanical ejection device can automatically disengage the circuit within 0.5 seconds to avoid the risk of short circuit fire
