DESCRIPTIONS:
The RSUN DT33 Series is an online double-conversion UPS designed for demanding, mission-critical power environments. Featuring three-phase input and output, it adopts active PFC technology to deliver an input power factor of up to 0.99, improving efficiency and reducing stress on the power grid.
Its space-saving, high-power-density structure maximizes installation efficiency, while advanced DSP control enables accurate regulation, real-time monitoring, and comprehensive protection.
The DT33 effectively shields critical loads from power anomalies including voltage surges, sags, transients, harmonics, and frequency fluctuations, providing stable and uninterrupted power for continuous operation.
