AC Surge Protective Devices (AC SPDs) play a vital role in preventing transient overvoltages caused by lightning strikes, switching operations, or grid fluctuations. These devices divert surge current safely to the ground, clamping the voltage within a secure range to protect connected electrical systems.AC SPDs are widely used to safeguard PLCs, variable frequency drives (VFDs), power panels, data centers, and precision instruments from insulation breakdown, board damage, and data loss caused by power surges.
A well-designed AC Surge Protective Device system provides comprehensive multi-level protection across your entire electrical network.
