Bicker Elektronik in Germany has developed a compact and durable 24V DIN rail uninterruptible power supply (UPS) with integrated Lithium-Ion backup battery.
The UPSI-2406DP1 DIN rail UPS bridges power failures, brownouts and flicker in the 24VDC power supply. The optimised power electronics means DC loads of up to 100W can be safely bridged.
The 2.5 Ah / 37 Wh lithium ion batteries provide a weight saving of up to 75 percent compared to conventional lead-acid batteries and can bridge a load of 96W for 15 minutes or a load of 25W for 60 minutes.
The DIN rail UPS is suitable for long-term 24/7 continuous operation in switch cabinets and decentralized self-sufficient designs in Industry 4.0, automation, robotics, image processing, medical and laboratory technology, transportation, process and safety technology, traffic monitoring, energy, communication, vending, payment systems and point of sale (POS) systems.
The UPS has over 500 charging cycles and the achievable DoD (Depth of Discharge) is significantly higher than for lead-acid batteries and the service life of Li-Ion cells is five times longer.
In normal operation the UPSI-2406DP1 makes the nominal mains input voltage available at the output, charges the Li-Ion battery pack and monitors the voltage thresholds at the input. If the voltage falls below the defined threshold, the system switches to UPS backup mode within fractions of a second and ensures an uninterrupted and regulated voltage supply for the connected 24V DC consumer at the output.
The intelligent distribution of the charging currents (PowerSharing) ensures that the upstream AC-DC power supply does not have to be oversized, but that the input power is kept constant and distributed accordingly to the load and Li-Ion battery charger. With a low load at the output, more energy flows into the charger and vice versa. This means energy consumption, space requirements and costs can be reduced.
