3. Kronos Operation And Descriptions
3.1 Operating Mode
The UPS provides the following operating modes:

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 200/115V, 208/120V and 220/127V. These can be
fine-tuned by ±8V.

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.
Always verify the load requirements and use ECO Mode with care.

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 200/115V, 208/120V and 220/127V. These can be fine-tuned
by ±8V. When the Converter mode is used and in the event of grid power failure, the power
will be 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.
