4.3 Typology
The Small Tower UPS is on-line, double conversion; the inverter included in
the UPS always supplies energy to the load, whether mains is available or not
(according to the battery autonomy time).
This configuration guarantees the best service to the User, as it supplies
clean power uninterruptedly, ensuring voltage and frequency stabilization at
nominal value. Thanks to the double conversion, it makes the load completely
immune from micro-interruptions and from excessive mains variations, and
prevents damage to critical loads.
The line connected to the UPS output is energized even during mains
failure, therefore in compliance with the prescriptions of IEC
EN62040-1, the installer will have to identify the line or the plugs
supplied by the UPS making the User aware of this fact.
