DESCRIPTIONS:

The RSUN DT33 Series is a high-efficiency, true online double-conversion UPS system engineered for demanding three-phase power applications. With input and output both in three-phase, it ensures consistent and clean power delivery for mission-critical infrastructure.

Equipped with active Power Factor Correction (PFC), the DT33 achieves an input power factor up to 0.99, significantly enhancing energy efficiency and reducing stress on upstream power components.

Thanks to its compact, high-power-density design, the DT33 is well-suited for space-constrained environments such as server rooms, data centers, and industrial control facilities. Its intelligent digital control platform offers enhanced system precision, real-time diagnostics, and superior fault management for increased operational stability.

Engineered to safeguard against a wide spectrum of electrical disturbances, including voltage dips, surges, transients, electrical noise, harmonic interference, and frequency instability, the DT33 Series ensures uninterrupted, high-quality power for sensitive and critical systems.
