Description
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.
