4 Operation
4.1 Operation Modes
The UPS is a double-conversion on-line UPS that may operate in the following modes:
Normal mode
The rectifier/charger derives power from the AC Mains and supplies DC power to the inverter while
floating and boosting charge the battery simultaneously. The inverter converts the DC power to AC
and supplies to the load.
Battery mode (Stored Energy Mode)
If the AC mains input power fails, the inverter, which obtains power from the battery, supplies the
critical AC load. There is no power interruption to the critical load. The UPS will automatically return to
Normal Mode when AC recovers.
KE 4256-5492 Keatec T Series 10-20kVA PF1.0 208Vac with Internal Battery 7.0 Touch Screen Users Guide English 20181118
This manual is for qualified personnel only Page 19
Bypass mode
If the inverter is out of order, or if overload occurs, the static transfer switch will be activated to transfer
the load from the inverter supply to bypass supply without interruption to the critical load. If the
inverter output is not synchronized with the bypass AC source, the static switch will perform a transfer
of the load from the inverter to the bypass with power interruption to the critical AC load. This is to
avoid paralleling of unsynchronized AC sources. This interruption is programmable but typically set to
be less than an electrical cycle e.g. less than 15ms (50Hz) or less than 13.33ms (60Hz).
ECO Mode
When the UPS is at AC Mode and the requirement to the load is not critical, the UPS can be set at
ECO mode to increase the efficiency of the power supplied. In ECO mode, the UPS works in Lineinteractive mode, so the UPS will transfer to bypass supply. When the AC is out of the set window, the
UPS will transfer from bypass to Inverter and supplies power from the battery. The LCD shows all
related information on the screen.
Maintenance mode (Manual Bypass)
A manual bypass switch is available to ensure continuity of supply to the critical load when the
UPS is out of order or in repair and this manual bypass switch bears for equivalent rated load.
