Ultra2x Technology

Why Ultra2X Technology Matters in Surge Protection

Most PQ Protection products come equipped with our exclusive Ultra2X Technology — and there’s a good reason for that.

If you ask a range of surge protection device (SPD) manufacturers what causes most SPD failures, the honest answer should be Temporary Overvoltage events (TOVs). While almost all SPDs rely on Metal Oxide Varistors (MOVs) to suppress surges, MOVs are designed to respond to fast, short-lived transients — events that last just milliseconds. They’re not built to handle prolonged or sustained overvoltage events.

TOVs, on the other hand, are slow-moving, 60Hz events that can last well beyond a half cycle — sometimes several seconds — and reach voltages up to 2x nominal levels. These often originate from utility grid anomalies, such as switching operations or faults. They don’t just threaten downstream equipment — they can damage the SPD itself.

Here’s where Ultra2X Technology makes the difference.

Unlike some SPDs that overreact to TOVs and end up failing in the process, PQ Protection SPDs avoid engaging with TOV events entirely. Instead, they stay focused on what SPDs are designed to do: mitigate fast, high-energy transients that threaten the reliability of mission-critical systems.

And for an SPD to truly protect mission-critical systems, it must be even more reliable than the systems it protects.

Ultra2X Technology is engineered to detect and ignore TOV conditions, preventing unnecessary stress and potential failure. It meets and exceeds the abnormal overvoltage safety requirements defined by UL 1449 4th Edition, and it ensures the SPD remains operational during and after an event — even if that event reaches up to 200% of nominal voltage.

Many other SPDs will permanently disconnect their protection circuitry during a voltage swell or overvoltage (as defined by IEEE 1159: 110%–180% of nominal), leaving your equipment exposed. Ours won’t. Instead, PQ Protection SPDs with Ultra2X stay online and continue providing transient surge protection — even in environments where sustained overvoltage conditions are known to occur.

If uninterrupted reliability matters, and traditional SPDs just don’t cut it, PQ Protection with Ultra2X is the smarter choice.
