UPSI-2401
24 V DC / 5 A
Continuous battery monitoring
Timer function
PC interface
The designed DC UPS UPSI-2401 protects connected consumer loads
from supply voltage fluctuations and interruptions. The μC controlled
DC UPS provides various protections. Among the most important
is the continuous battery monitoring feature. This ensures that
sufficient capacitance remains in the battery to guarantee the supply
of consumer loads in case of power failure. Additionaly the UPSI-2401
offers a load sensor and a timer function. The timer function was
integrated and allows a timer-controlled switch-off of the UPS.

Product specific data
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 app. every 10 minutes, in case of “Battery defect“ notification the LED
flashes red/green (optional sginaling contact)
Power consumption App. 50 mA
Shutdown (input) Signal to switch off the PSU in UPS mode. The level has to be 7…12 VDC and has to be connected ≥60 msec.
The UPS switches off after app. 15 sec.
Shutdown suppression During system start-up the shutdown signal is suppressed for app. 2 minutes.
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.
Load sensor Switch-off in UPS mode <10 Watt
Timer function 2 min – 6 min – 20 min – off, adjustable via DIP switch
Back up time App. 30 min at 1 A / app. 8 min at 3 A / app. 3 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.
