On-line mode:
if mains power is available and the UPS has completed the startup procedure,
on-line mode is automatically activated.
-> If necessary, the battery pack is also charged in this operating mode.
Display/alarm signal: in on-line mode is indicated by the illumination of the ON
Line display as well as the current value of the output load (here 50%). No
audible alarm signal.
A.V.R. mode:
Within certain limits, A.V.R. mode compensates for over- or under-voltage in
the power supply without drawing current from the batteries. This reduces the
transfer voltage range at the UPS output compared to the mains power supply.
The values are specified in the Technical Data.
Display/alarm signal: A.V.R. mode is indicated by the illumination of the ON
Line and ON A.V.R display as well as the current value of the output load (here
50%). No audible alarm signal.
