5.1 ON LINE OPERATIONS.
ON LINE operation consists of double conversion operation in conjunction with mains absorption with very low
distortion. This enables the UPS to supply a voltage that is fully stabilised in frequency and amplitude, regardless of
any interference in the mains power supply.
ON LINE operation provides three operating modes according to mains and load conditions:
•
“Normale” mode .
This is the most frequent operating condition: the energy is drawn from the primary mains power supply and is
converted and used by the inverter to generate the output voltage to power the loads connected.
The inverter is constantly synchronised in frequency with the auxiliary mains to enable load transfer (due to an
overload or inverter shutdown) without any break in the power supply to the load.
The battery charger supplies the energy required to maintain or recharge the battery.
• “Bypass” mode .
In case of inverter failure, the load is automatically transferred onto the auxiliary mains without any interruption in
the power supply. This procedure may occur in the following situations:
- in the event of a temporary overload, the inverter continues to power the load. If the condition persists, the UPS
output is switched onto the auxiliary mains via the automatic bypass. Normal operation, which is from inverter,
returns automatically a few seconds after the overload disappears.
- when the voltage generated by the inverter goes is out of tolerances due to a major overload or a fault on the
inverter.
- when the internal temperature exceeds the maximum value allowed.
• “Battery” mode .
In the event of a mains failure (micro interruptions or extended black-outs), the UPS continues to power the load
using the energy stored in the battery. The Expert Battery System keeps the user constantly informed on the bat-
tery status and on the back-up time available.
5.2 OPERATION IN HIGH EFFICIENCY “ECO-MODE”
Operation in ECO-MODE can increase overall effi ciency by up to 98% and, at the same time, energy savings can
be achieved by selecting and programming daily or weekly time intervals in which the applications are powered
directly from the auxiliary mains. If the mains supply fails, the UPS will automatically switch onto the inverter and
continue to supply power to the load through the batteries.
Unlike ON LINE operation, operation in ECO-MODE does not provide perfect stability in frequency and voltage; use
of this mode should therefore be carefully evaluated according to the level of protection required by the applica-
tion.
