PowerWalker VFI 20K CPG PF1 3/3 BI uninterruptible power supply (UPS) Double-conversion (Online) 20 kVA 20000 W 1 AC outlet(s)

The PowerWalker VFI CPG 3/3 PF1 series is a professional commercial solution
built in double conversion technology with power factor 1.0. Equipped with
three-level inverter topology, it results in high efficiency reaching 95.5% in
Line Mode and even 98.5% in ECO Mode. The series ensures low harmonic
distortions and precise voltage regulation (1%). All phases have Active Power
Factor Correction.
Thanks to its modern design, the VFI CPG series reaches a very high power
density (kVA output in relation to the size/volume of the unit). All models of
this series offer generator support, dual input and allow parallel operation up
to three units. Each unit is equipped by default with SNMP Card to increase
control over the unit and offer embedded monitoring over IP.
For this model battery numbers can be adjusted (between 32 and 40pcs,
except 10K unit), allowing more flexibility and compatibility with existing
battery banks. The three stage extendable charging design also enhances
battery performance over its life time.
For safety reasons this series has been equipped with backfeed protection
(reverse feed) in order to avoid power transfer to the input terminal in case of
mains failure. On demand we can modify unit to include isolation transformer
or negative power absorber.
