TAIXI Surge Protector SPD Lightning Protection Performance
The surge protector SPD uses metal oxide varistors or gas discharge tube technology rated to conduct 20KA to 40KA of transient current within nanoseconds, limiting voltage rise to levels within equipment component ratings. Operating voltage ratings span 12V through 1000V DC, covering battery systems, EV charging infrastructure, solar photovoltaic arrays and hybrid generation platforms without requiring separate protection stages. Two-pole and three-pole configurations protect single-phase and three-phase circuits respectively, accommodating both residential solar installations and commercial photovoltaic power generation facilities. Response time measured in nanoseconds means surge protection activates before equipment sensors detect overvoltage, preventing nuisance shutdowns and false alarms in automated battery management and inverter control systems. Thermal protection ensures the surge protector SPD disconnects from the circuit if internal dissipation exceeds design limits, preventing component failure and maintaining system availability during extended lightning activity.
