Ultra2X technology has been specifically designed to meet and exceed the safety requirements for the abnormal over-voltage testing of UL 1449 Edition 4.

Many SPD’s permanently disconnect all protection from the circuit during an over-voltage or swell event as defined by IEEE 1159 - an increase in the RMS voltage level to 110% - 180% of nominal. Ultra2X technology allows the SPD to experience an abnormal over-voltage or swell up to twice its nominal operating voltage and still remain operational during and after this event. Ultra2X technology allows the SPD to provide reliable and continuous protection to your sensitive electronic equipment.

Ultra2X technology is recommended for all sites and especially ones where sustained over-voltages are known to occur and where failure of traditional SPD technologies cannot be tolerated.
