RODUCT ESCRIPTION
The UB40.241 is an uninterruptible power supply controller (DC-
UPS controller), which is used in combination with a 24V power
supply and an external 24V-battery pack to bridge power
failures. When the power supply provides sufficient voltages,
the DC-UPS controller charges the battery. When the power
supply voltage fails, the energy stored in the battery is released
to the DC bus in a regulated process.
A unique feature is the battery charger, which can balance two
unmatched batteries and which includes two independent
battery testers for the two 12V batteries connected in series.
This feature makes matching batteries unnecessary and allows
for precise battery charging, testing and optimized usage of the
battery capacity to achieve the longest battery service life.
The device includes various battery diagnostic functions
including a battery-low pre-warning signal that ensure a reliable
operation of the entire system. Furthermore, temperature
controlled charging extends the life of the batteries. It also
includes a selectable buffer time limiter as well as "Ready",
"Buffering" and "Replace battery" contacts. For safety and
maintenance, an inhibit-input signal is included to enable phases
without enforced buffering.
