UBC10.241, UBC10.241-N1
U–Series
24V, 10A, DC-UPS
May. 2008 / Rev. 1.1 DS-UBC10.241-EN
All parameters are specified at an input voltage of 24V, 10A output load, 25°C ambient and after a 5 minutes run-in time
unless otherwise noted. It is assumed that the input power source can deliver a sufficient output current.

19. PROTECTION FEATURES
Output protection Electronically protected against overload, no-load and short-circuits
Output over-voltage protection
in buffer mode
typ. 32Vdc
max. 35Vdc
In case of an internal defect, a redundant circuitry
limits the maximum output voltage. The output
automatically shuts-down and makes restart attempts.
Degree of protection IP20 EN/IEC 60529
Penetration protection > 3.5mm E.g. screws, small parts
Reverse battery polarity protection yes Max. –35Vdc;
Wrong battery voltage protection yes Max. +35Vdc (e.g. 24V battery instead of 12V battery)
Battery deep discharge protection yes The limit is battery current dependent
Over temperature protection yes Output shut-down with automatic restart
Input over-voltage protection yes Max. 35Vdc, no harm or defect of the unit
Internal input fuse 25A, blade type No user accessible part, no service part
