DHF SS SERIES UPS
Range: 1 kVA to 20 kVA (1:1/3:1)
The DHF Series 1 kVA to 20 kVA UPS system is a single-phase UPS that uses
advanced technology for a dependable power supply. The DHF Series utilises high
frequency online double conversion technology, providing stable output and
protection against fluctuations. Controlled by Digital Signal Processing (DSP) for accuracy
and efficiency, it includes active power factor correction (APFC), achieving an input power
factor of up to 0.99. This reduces reactive power and enhances energy efficiency. The
system offers output power factor options of 0.9 or 1.0 to meet different load needs.
With a broad input voltage range and a frequency range of 40 to 70 Hz, along with autosensing
and 50/60 Hz conversion, it adapts to various power environments. The “cold start”
function allows activation without external power, which is essential in emergencies.
Battery configurations are flexible, supporting 16 to 20 batteries with digitally controlled
charging for optimal health.
