ENERAL ESCRIPTION
Power failures or voltage fluctuations can cause
damage and downtime, which usually costs a lot of
time and money. The UB10.241 together with a
battery module offers a reliable and economical
protection for 24V applications.
The output is isolated from the input, which allows
an easy separation of buffered and non-buffered
branches. The energy of the battery will not be
wasted by uncritical consumers.
In times when the power supply provides sufficient
voltage, the DC-UPS charges the 12V battery. In
case the input power fails, the battery voltage will
be boosted to a 24V level and the energy will be
released in a regulated process to the load.
The included battery management incorporates a
battery charger, a deep-discharge protection and
an overload protection to achieve a long service life
of the battery.
The availiability of the DC-UPS is reported by lamps
and relay contacts. The DC-UPS automatically
checks the installation, the battery fuse and the
quality and presence of the battery. Diagnosis is
very easy, thanks to clear understandable indicators
and relay contacts for remote signaling.
Extensive protection features protect the unit
against wrong battery polarity, wrong battery
voltage, wrong input oltage or output overloads.
