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.
