4.1. ONLINE
OPERATION
A special feature of the Green Power 2.0 series is the ONLINE double conversion in conjunction with low distortion mains power
absorption. In Normal Mode (on inverter), the UPS can supply a voltage that is fully stabilised in frequency and amplitude, regardless
of any interference in the mains power supply, within the most stringent classification of UPS regulations.
ONLINE operation provides three operating modes according to mains and load conditions:
• Inverter mode
This is the most frequent operating condition: energy is drawn from the primary mains power supply and converted and used by
the inverter to generate the output voltage to power the connected loads.
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 the event 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
on to the auxiliary mains via automatic bypass. Normal operation, which is from the inverter, returns automatically a few seconds
after the overload disappears.
- When the voltage generated by the inverter goes outside the limits 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 power cuts), the UPS continues to power the load using the energy
stored in the battery.
4.2. OPERATION IN HIGH EFFICIENCY MODE
The UPS has a selectable, programmable economy operating mode (
ECO MODE
) that can increase overall efficiency by up to 99%
for energy saving purposes. If the power supply fails, the UPS will automatically switch onto the inverter and continue to supply
power to the load by drawing energy from the battery.
This mode does not provide perfect stability in frequency and voltage like the
NORMAL MODE
. Therefore the use of this mode
should be carefully evaluated according to the level of protection required by the application.
With the optional board Net Vision (see chapter 7.7) specific daily or weekly time intervals can be selected and programmed to power
applications directly from the auxiliary mains.
ECO MODE
operation provides very high efficiency, since the application is powered directly from the auxiliary mains via the auto-
matic bypass under normal operating conditions.
To activate
ECO MODE
go to
MAIN MENU > COMMANDS > ECO MODE
and select
ACTIVATE ECO MODE
. To disable
ECO
MODE
, select
RETURN TO NORMAL MODE
.
