Operating Mode
The UPS provide 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.
