The UB10.245 uninterruptible power supply (UPS) controller along with a standard 24V power supply and 1 12V battery can bridge power failures or voltage fluctuations. This unit can supply and bridge both a 24V load as well as a 12V load at the same time. The 12V is generated by a DC/DC converter from the 24V output. Therefore systems that utilize 24V control circuits and require 12V for e.g. remote radio telemetry can be supplied with only 1 UB10.245 DC-UPS controller. 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.
