5.1. Online Mode (norl)
Energy is drawn from the mains input. Loads are supplied through the rectifier and the inverter. The
AC voltage at the input is converted to a DC voltage by the rectifier. The inverter converts this DC
voltage to an AC voltage with a stable sinusoidal waveform, amplitude and frequency. Output
voltage is sinusoidal and has a regulated amplitude and frequency. It is independent from the input
voltage. The loads are not affected by the negativities of the mains.
* It shows the UPS is operated in “normal mode”.
* It shows inverter output voltage.
If the mains voltage and frequency are in certain range, Online Operation is possible. For the mains
limits for Online Operation, please see
Appendix-2 Technical Specifications
The upper limit of mains voltage is independent from the load percentage
and it is 270V. UPS
switches to Battery Operation mode when the mains is over 280V. The mains is required to
decrease below 260V for UPS to return Online Operation.
Online Operation Conditions;
In case Online Operation (norl) is set as operation mode of UPS, the mains is within the limits
and/or if there is no abnormal condition (overheat, overload, failure…etc.) UPS operates in
Online Operation. Except for failures, as soon as the abnormal conditions are eliminated, UPS
switches to Online Operation automatically.
In case Eco Operation is set as operation mode of UPS and the voltage and frequency is out of
the bypass limits but within the rectifier limits, UPS swithes to Online Operation.
