This uninterruptible power supply (UPS) controller

UBC10.241 with integrated battery is a compact

addition to standard 24V power supplies to bridge

power failures or voltage fluctuations. Expensive

downtimes, long restart cycles and loss of data can

be avoided.

The DC-UPS includes a professional battery

management system which charges and monitors

the battery to achieve the longest battery service life

as well as many diagnostic functions that ensure a

reliable operation of the entire system.

A unique feature of the UBC10.241 is that only one

12V battery is required to buffer the 24V output.

This makes matching batteries unnecessary and

allows a precise battery charging and testing.

The UBC10.241 has one integrated 12V 5Ah high

current VRLA battery, which is easy to change.

In addition to the UBC10.241, a separate UPS

controller (UB10.241) which requires an external 12V

battery is available when a longer buffer time is

required.

CHECK WIRING AND BATTERY QUALITY TESTS The DC-UPS is equipped with an automatic “Check Wiring” and “Battery Quality” test. “Check Wiring” test: Under normal circumstances, an incorrect or bad connection from the battery to the DC-UPS or a missing (or blown) battery fuse would not be recognized by the UPS when operating in normal mode. Only when back up is required would the unit not be able to buffer.

They degrade slowly beginning from the production and need to be replaced periodically. The design life figures can be found in the individual datasheets of the batteries and usually is specified according to the Eurobat guideline or according to the manufacturer’s specifications.

UBC10.241, UBC10.241-N1 24V, 10A, DC-UPS U–Series 28.3. USING THE INHIBIT INPUT The inhibit input disables buffering. In normal mode, a static signal is required. In buffer mode, a pulse with a minimum length of 250ms is required to stop buffering. The inhibit is stored and can be reset by cycling the input voltage. For service purposes, the inhibit input can also be used to connect a service switch. Therefore, the inhibit signal can be supplied from the output of the DC-UPS. Fig.
