Operating Mode
The UPS provides the following operating modes:
(1)
Normal Mode (Online Mode):
In Normal mode, grid power is passed through Rectifier then used to charge the
battery and provide power through the Inverter simultaneously. Different output
voltages settings can be set in VFI mode. The three options are 380/220V, 400/230V
and 415/240V. These can be fine-tuned by ±8V.
(2)
Economy Mode (ECO):
Economy Mode effectively improves overall efficiency. In ECO Mode grid power is
routed through the Static Switch to the load. At the same time, grid power continues
to charge the battery in DC/DC mode through Rectifier following the same setup as
VFI Mode. Inverter is also kept ready to switch power supply modes at any time. If
VFI mode is set then power can be quickly routed from Bypass to Inverter.
Attention: In ECO Mode the power supply frequency and voltage will be less stable.
Please check the load requirements and use ECO Mode with care.
(3)
Converter Mode:
Converter Mode allows the user to provide a power supply with constant voltage and
constant frequency based on their power requirements. The frequency can be set to
50HZ or 60HZ. The voltage options are 380/220V, 400/230V and 415/240V. These
can be fine-tuned by ±8V. When Converter mode is used, in the event of grid power
failure then power is provided from the battery in Back-up mode. In the event of the
battery running low, UPS overload, Inverter failure or module overheating, the entire
system will shut down.
