LED display 3-colour-LED for „Power ok” (green), „Power Fail” (orange),
„Battery low” (red/orange flashing) and „Battery defect”
(red/green flashing), short circuit at output/overload (red)
Battery monitoring Battery test is carried out in normal mode approx every 10 minutes,
in case of “Battery defect“ notification the LED flashes red/green
Power consumption App. 80 mA
Shutdown-suppression During system start-up the shutdown signal is suppressed for app. 2 min.,
because any interface testing of Windows and a simultaneous power
failure would switch off the module. This suppression is only active when
the module is switched on the first time!
Reboot function If power fails and then returns during the shutdown mode of Windows®,
the operating system will ‚lock‘ with the message „Your PC is now safe“.
The reboot function restarts the system after about 10 seconds.
Back up time App. 33 min at 1 A / app. 9 min at 3 A / app. 3.5 min at 5 A
(measured at +20 °C)
The service life of the batteries is app. 4…5 years at +20 °C and will decrease by half with each temperature increase of 10 °C according
to EUROBAT.
