DESCRIPTIONS:

The RSUN DT33 Series is a true online double-conversion UPS designed for high-load, mission-critical applications. With three-phase input/output and built-in PFC, it delivers a power factor up to 0.99 enhancing power quality and reducing input strain.

Thanks to its high power density, it fits space-constrained environments, while advanced DSP control ensures precise operation, system stability, and intelligent fault protection.

The DT33 effectively shields connected equipment from electrical disturbances such as sags, surges, spikes, harmonics, and frequency deviations, ensuring uninterrupted, clean power at all times.
