PULS UB20.241 DC-UPS Control Unit
Introduction
The UB20.241 uninterruptible power supply controller (DC-UPS) is used in addition to a 24V power supply and batteries to bridge power failures or voltage fluctuations. This configuration can prevent expensive downtimes, long restart cycles, and loss of data.
A unique feature of the UB20 series is the constant voltage in battery mode, which will not change as the batteries discharge. The buffer voltage in battery mode can be set to four different output values. Another feature is the utilization of two independent battery chargers for the two 12V batteries in the 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 UB20.241 includes many battery diagnostic functions that ensure the 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 replacing battery contacts. For safety and maintenance, an inhibit input signal is included which prevents a battery backup.
