The VFI1000QS is a true online double conversion UPS System providing the highest degree of
power protection for your load.
Blackouts
In the event of a power cut, the VFI1000QS
will seamlessly transfer to battery power.
This is true “no-break” with zero transfer
time.

Voltage
The output remains constant regardless of
what is happening at the input. Momentary
sags and spikes are effortlessly taken care of.
Prolonged under and over voltages do not
require the VFI1000QS to enter into battery
mode due to its wide input voltage window.
Noise
Transients
Harmonics
Distortions on the input mains voltage are
not transferred to the load. The load is
powered from the UPS inverter at all times,
which is “ReGenerating” a new AC power
waveform clean of any power contaminants
on the input.
Frequency
The VFI1000QS can be set to frequency
conversion mode, with a fixed output
frequency. This means that in situations
where the input frequency may be unstable,
for example when on generator power, the
load still receives the required voltage and
frequency.
The UPS is composed of mains input, EMI/RFI filters, rectifier/PFC, inverter, battery charger,
DC-to-DC converter, battery, dynamic bypass and UPS output.
