24V DC UPS WITH LI-ION BACKUP BATTERY: SAFE PROTECTION AGAINST POWER FAILURES


sufficient solutions for Industry 4.0, automation, robotics, image processing, medical and laboratory technology, transportation, process and safety technology, traffic monitoring, energy, communication, vending, payment systems/POS, and many more. What are the advantages of Li-Ion technology over lead-acid batteries? With regard to system integration and


Plant downtimes, system failures and loss of data can become risky and costly. For minimising this risk, Bicker Elektronik presents UPSI-2406DP1 with durable Li-Ion backup. The DC UPS modules bridge power failures, brownouts and flicker in 24VDC supply network and are approved to IEC/UL/CSA 61010-1 / -2-201. The new intelligent UPSI-2406DP1 is ideal for long-term use in switch cabinets and decentralised self-sufficient solutions, protecting 24V applications like industrial and medical PCs, controls, motor drives, actuators, sensors, measurement devices and safety technology.


T


he reliable and fail-safe DC power supply of embedded IPCs, controls,


motor drives, sensors, measurement devices and safety technology is of fundamental importance in networked high-tech systems worldwide and in almost all fields of application. Plant downtimes, system failures and loss of data can become risky and costly. By using intelligent DC UPS systems, this risk can be significantly minimised and the uninterruptible power supply and thus reliability is assured. For this purpose, the power supply specialist Bicker Elektronik, Donauwoerth/ Germany, presents a particularly compact and durable solution with an excellent price-performance ratio: the new DC UPS module UPSI-2406DP1 with integrated Lithium-Ion backup battery, which bridges power failures, brownouts and flicker in the 24VDC power supply.

SOLUTION WITH SUPERCAPS In addition to the UPSI-2406DP1 with Li-Ion battery, Bicker Elektronik offers with its sister - model UPSI-2406DP2, a fail-safe DC UPS solution based on absolutely maintenance-free supercaps (ultracapacitors) for short and medium bridging times. www.bicker.de/en/upsi-2406dp2


24V DC UPS with integrated Li-Ion battery protects against plant downtime and data loss caused by power failures


economy (TCO), energy storage devices with space and weight savings of up to 75% can be realised with Lithium-Ion cells compared to conventional lead- acid batteries. Lithium is the lightest metal in the periodic table and has ideal electrochemical properties for providing high specific energy densities (Wh/kg). Under comparable operating conditions the number of charging cycles (cycle life ≥500 for UPSI-2406DP1) and the achievable DoD (Depth of Discharge) are significantly higher than with lead-acid batteries and the service life of Li-Ion cells is even up to five times longer. Reliable bridging of longer power failures In normal operation, the system


electronics of the UPSI-2406DP1 make the nominal mains input voltage available at the output, charge the Li- Ion battery pack and monitor 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. With a capacity of 2.5 Ah / 37 Wh, the internal Lithium-Ion battery provides enough energy to bridge a load of 96 Watt for approx. 15 minutes or a load of 25 Watt for approx. 60 minutes. 'Power sharing' with intelligent input current detection 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. Thus energy consumption, space requirements and costs can be reduced. 'Smart Battery Lock' prevents battery discharge The battery management system


prevents the integrated battery pack from leakage discharging when the
