The unique UB40 module maintains a constant voltage in battery mode. Most modules on the market in battery mode simply allow the battery voltage to flow to the load. This causes the voltage supplied to critical loads to fluctuate from 27-28V DC when the batteries are charged to 20V when the batteries are discharged. Furthermore, any power surge, which can cause a voltage spike due to a rebound effect, is directly reflected in the output of most DC UPS modules on the market. In contrast, the UB20 module has a boost-buck converter that maintains a stable output voltage throughout the entire power outage, extending runtime and keeping your loads protected.
Furthermore, the charging system for the two 12V batteries connected in series is independent. This allows for increased battery life and the use of batteries from different manufacturers and production batches, maximizing their capacity and extending their lifespan.
The UB40 module also includes a sophisticated battery health diagnostic system, providing proactive warnings so that batteries can be replaced before capacity loss is detected too late. It also allows for charging voltage compensation based on battery temperature using a PT1000 temperature sensor (supplied separately). We can select the runtime to safeguard battery capacity if a very long runtime is not required, maintaining capacity for when we need to continue operating the next time we turn on the batteries, before they have had a chance to recharge. It has different alarm relays for the equipment status, battery status and battery mode warning, as well as LEDs indicating charging status, batteries not connected, failure of any of the batteries and other warnings that allow us to easily identify the status of the equipment and any problems in our application.
