Power supply for safety-relevant applications.

An integrable and space-saving DC UPS solution for applications in industry and medical technology has been presented by Bicker Elektronik. The 24V emergency power supply with the particularly safe and durable LiFePO4 battery technology bridges power failures, voltage dips or flickers and thus effectively avoids system failures and data loss. Consisting of the UPSI-2406 charging and control unit and the BP-LFP-1325S battery pack, the compact DC UPS solution is ideal for protecting sensors, measurement and control systems, embedded IPCs, emergency lighting, security technology and many more. The new UPS management software 'UPScom' with cross-platform technology and intuitive user interface is available for download free of charge and offers extensive functions for monitoring, parameterisation and messenger services.

Particularly safe and durable LiFePO4 battery technology.
The 10-year BP-LFP-1325S (33Wh) battery pack with lithium iron phosphate (LiFePO4) battery technology impresses with over 6,000 charge and discharge cycles and an extended temperature range from -20 to +55°C. The high-performance battery management system (BMS) for optimising service life and safety monitors and controls the complete charging and discharging process of each battery cell of the energy storage unit. The cell balancing function also ensures that all cells are charged evenly so that the full capacity of the LiFePO4 battery pack remains permanently usable. The BP-LFP-1325S has IEC 62133-2 safety approval and the UN 38.3 transport certificate.

Intelligent UPS charging and control unit.
The UPSI-2406 charging and control unit for flexible and space-saving system integration is connected to the battery pack via two lines. In addition to the power transmission line (BAT PWR), all relevant operating data of the energy storage unit are continuously monitored and controlled on the data line (BAT DATA) via I2C interface. The PowerSharing function ensures that the input power is kept constant and distributed to the load and battery charger in an appropriately adapted manner. When the load at the output is low, more energy flows into the charger and vice versa. In the event of voltage dips or power failures, a MOSFET disconnects the input within a few microseconds and the connected load is supplied from the energy storage without interruption. In backup mode, the UPSI-2406 provides a constantly regulated DC output voltage. In battery mode, the minimum load detection monitors the output load to be supplied from the energy storage device and automatically disconnects the energy storage device from the charging and control unit if the load at the output falls below a certain limit value. This prevents the energy storage unit from being unnecessarily emptied. In addition, the UPSI-2406 has a USB and RS232 interface for data communication as well as a relay contact.

UPS management software 'UPScom' with cross-platform technology.
The completely newly developed UPS management software 'UPScom' is available for download free of charge for Microsoft® Windows and Linux. The software enables the controlled shutdown and switch-off of the connected devices during a power failure. For setting and pre-programming all parameters of the DC UPS system as well as real-time monitoring with charge status display, the responsive WEB-UI is called up in a web browser. The adjustable parameters include load sensor (mA), shutdown delay, maximum backup time, minimum charge capacity before system start, notifications via e-mail. The UPS management software 'UPScom' uses the new WebAssembly (WASM) architecture, which is executable in most current web browsers. 'UPScom' runs on x86 compatible systems and also on most ARM-64 based systems under Microsoft® Windows and various Linux distributions.

Shutdown & reboot function for stand-alone embedded IPCs.
In the event of a "power fail", the UPS signals the failure of the supply voltage via the integrated USB or RS232 interface, so that a controlled shutdown of the computer system is initiated and valuable data is saved. A script (batch) can also be executed before the system is shut down in order to process own application-relevant processes. The integrated reboot function of the DC UPS automatically initiates the restart of the supplied IPC after the supply voltage has been restored, without the need for time-consuming on-site intervention by a service employee, e.g. in the case of completely self-sufficient computer systems at inaccessible locations.
