PULS UB20.241 DC UPS

The PULS UB20.241 DC UPS uninterruptible power supply has been designed to be connected on the output side of a 24 VDC power supply and back up critical 24 VDC loads such as PLCs, RTUs and HMIs in the event of a power failure.

The unit manages and monitors two 12 V batteries that are connected in series. When power is present, the UPS charges and monitors the batteries as well as isolating the 24 VDC load connected to its output from the input supply. When it detects that power has been lost, it provides output power from the batteries while continuing to monitor each battery.

The device can be used with batteries that range from 3.9 to 130 Ah. It is powerful yet compact, measuring as little as 46 mm in width.

Other features include adjustable output voltage in buffer mode and negligible voltage dips or overshoots when transitioning from normal to buffer mode. The unit also has extensive diagnostic and monitoring functions.
