Sag-Free Fluctuation-Free - SFCube​
Unlocking SFCube: A closer look inside the power wonder

The TSi-SFCube series (SFCube meaning SFFF – Sag Free Fluctuation Free) ensures uninterrupted operation over a wide range of sag and surge scenarios. With a rapid compensation time of 1 waveform, it aligns seamlessly with the ITIC curve standards, ensuring a consistent power supply to your electronics. It will control, for any length of time, up to a 50% sag event, and bring it within a usable voltage of +/-10%.
