DESCRIPTIONS:
The RSUN DT33 Series is a high-performance online UPS with true
double-conversion and three-phase input/output, engineered for
critical high-power applications. With integrated PFC, it delivers
up to 0.99 input power factor, enhancing energy efficiency and
reducing upstream load impact.
Its compact, high-density design saves space, while advanced
digital control ensures precise operation, strong fault tolerance,
and intelligent self-diagnostics.
The DT33 reliably protects sensitive equipment from power
disturbances such as surges, sags, transients, harmonics, and
frequency instability guaranteeing stable, clean power for
demanding environments.
