General Description of A UPS
UPS of this series are true on-line, double conversion UPS (classification-code VFI-SS-111); the inverter supplies the
load under normal operating conditions, whether mains is available or not (according to the battery autonomy time).
ATTENTION:
The UPS output is energized even during mains failure, therefore in compliance with the prescriptions of
EN 62040, the installer must label the outlets, plugs or lines supplied by the UPS, making the user aware
of this fact.
This true online concept guarantees great advantage to the user, as it supplies clean, continuously regulated power and
guarantees a stabilized voltage. Thanks to the double conversion principle, the load will be protected from micro-
interruptions due to excessive mains variation. It prevents damage to the critical load.
