Send us the load power consumption and required backup time; we will help you choose the right backup system and power supply.
Reliable backup for industrial automation
The UPSI-2406R2DP3MB protects control, communication and measurement systems from outages, voltage dips and voltage fluctuations on the 24V supply line. If the power supply fails, the integrated LiFePO₄ battery takes over; switching to backup mode takes less than 600 µs. It is therefore suitable for industrial computers, PLCs, IIoT gateways, network devices, sensors, and measurement, control and safety systems.
Up to 6 A and 144 W for protected 24VDC loads, with regulated output voltage in backup mode.
USB-C (HID-UPS) for IPC and RS485 Modbus RTU for PLC/SCADA. Power Fail relay contact is also available.
The LiFePO₄ battery with BMS, 33 Wh capacity and up to 6 000 cycles is suitable for long-term operation in a control cabinet.

For new control cabinets and modernisation of existing equipment
The UPSI-2406R2DP3MB is a suitable choice for new industrial control cabinets where you want to protect 24V control systems from frequent short outages, voltage dips and supply line fluctuations from the outset.
It helps keep PLCs, computers, PROFINET and Ethernet switches, and other systems running while the rest of the equipment stops safely or a stable power supply is restored. DIN rail mounting makes it easy to integrate into a new project or an existing control cabinet during modernisation.

LiFePO₄: safe energy for years of operation
The integrated LiFePO₄ battery combines stable chemistry with a service life of up to 10 years and up to 6 000 complete charge and discharge cycles. The Battery Management System continuously monitors charging and discharging and protects the battery module in the event of a fault.
Compared to a lead-acid battery, LiFePO₄ offers significantly higher cycle endurance and the full rated capacity can be used. The lower need for maintenance and replacements has a positive impact on the total costs over the life of the device.

Backup time curve by output power
This curve shows the expected backup time of the UPSI-2406R2DP3MB depending on output power. It is a practical aid when designing protection: at lower power, the 33Wh LiFePO₄ battery supplies energy for longer; at higher power, backup time is shorter. The actual value depends on battery condition, ambient temperature and operating conditions.

You can set the UPS parameters from the browser
UPScom software enables online monitoring and configuration of the DC UPS through an intuitive web interface. It displays the charge status and allows parameters to be set without a complicated service intervention.
For normal use, USB-C also works as a standard HID-UPS: supported operating systems recognize it as a UPS or battery without installing a separate driver. If a custom procedure is to be performed before the system shutdown in the event of a power outage, UPScom can control it with a script.
- load sensor in mA and minimum load detection,
- shutdown delay, maximum backup time and minimum charge before startup,
- email notifications in case of loss of connection, power outage or system shutdown,
- controlled shutdown and optional execution of a custom script before the system shutdown.
Safe shutdown and automatic computer restart
After detecting a power outage, the UPS informs the connected system via integrated interfaces. The computer can properly save data and shut down instead of being suddenly disconnected. When input voltage returns, the Reboot function automatically restarts the powered device — especially useful for autonomous systems in hard-to-reach places.
USB-C in HID-UPS mode is recognized by the operating system as a standard UPS without a special driver. RS485 Modbus RTU gives the possibility to read status data and control backup logic directly from PLC or SCADA.

Practical features that help in real operation
The UPSI-2406R2DP3MB does more than bridge a power outage with a battery. It continuously evaluates the load, stored energy status and configured shutdown procedure, helping protect data and connected equipment without unnecessary downtime.
The DP3 variant can handle up to 192 W of power for a short time when starting the load. The power reserve is monitored in a time window, so it helps with start-up peaks, but does not represent permanent extra power.
The shutdown logic can be linked to the minimum state of charge, maximum backup time, a time schedule or a drop in load. This gives the control system time to save data, stop the process and only then disconnect the output.
Good airflow and a reasonable depth of discharge benefit the LiFePO₄ battery. Correctly sizing the power to be backed up therefore protects the equipment and also extends battery life.
Immunity and protection functions
The device is designed for demanding industrial operation at temperatures from −20 to +50 °C. It complies with IEC/EN/UL 61010-1 and IEC/EN/UL 61010-2-201; the high-performance LiFePO₄ battery pack has IEC 62133-2 safety certification.
Higher surge immunity helps maintain stable UPS operation even in environments with fast transients and surges on the power line.
Immunity to fast transients according to EN 61000-4-4: 2 kV, criterion A. Surge immunity according to EN 61000-4-5: ±0,5 kV L–N and ±1 kV L–PE/N–PE, criterion A.
Protection against input polarity reversal, overcurrent and output short circuit. BMS monitors the safe operating limits of the battery.
Power-fail timer, Battery Start, minimum load detection and automatic output disconnection protect the battery from deep discharge.

Frequently Asked Questions
How long can the UPSI-2406R2DP3MB keep a device running during an outage?
Backup time is not fixed. It depends on actual power consumption, temperature, battery condition and the selected settings. The battery has 33 Wh; for accurate sizing, send us the load power consumption and required backup time.
Is it possible to monitor the UPS from a PLC?
Yes. The RS485 interface with Modbus RTU is designed for communication with a PLC or SCADA. The UPS can be connected to an industrial computer as a HID-UPS via USB-C.
What is Battery Start?
The function allows you to manually start the 24V output directly from the battery when it is sufficiently charged, even without the input voltage present.
What happens when current draw is low or the battery discharges?
The UPS can detect a current drop below the set level and disconnect the output after the load has been correctly switched off. At the same time, it protects the battery from deep discharge.
Is LiFePO₄ or a supercapacitor better?
LiFePO₄ makes sense for longer backups. The supercapacitor is especially suitable for short backups and an extremely high number of cycles. The choice is determined by the required operating time in the event of a power outage.

What is the battery lifetime?
The LiFePO4 battery can achieve up to 6,000 charge cycles depending on operating conditions.
How fast does the UPS switch during a power failure?
The transfer from normal to backup mode is very fast, typically within 600 µs, so connected devices usually do not detect the interruption.
How can the UPS be monitored or configured?
The UPS can be connected via USB-C (HID-UPS) or RS-485 using Modbus RTU. Advanced configuration and monitoring are available via UPScom software.
What does HID-UPS mode mean?
In HID-UPS mode, the device is recognized by the operating system as a standard UPS without the need for additional drivers, enabling automatic power management and safe system shutdown.
How does the UPS signal a power failure?
The UPS signals its status via a potential-free relay contact (power fail) and diagnostic information available through communication interfaces.
What is the Power Sharing function?
Power Sharing ensures intelligent distribution of input power between the load and battery charging, eliminating the need to oversize the power supply.
What does minimum load detection mean?
The UPS can detect when the load drops below a defined threshold and automatically switch off the output, for example after a controlled system shutdown.
What is the Battery Start function?
Battery Start allows the UPS output to be activated directly from the battery even without input power (only if the battery is sufficiently charged).
What is the power-fail timer?
The power-fail timer allows you to define a delay before initiating a controlled shutdown of connected devices after a power failure.
What happens when the battery is fully discharged?
The UPS protects the battery against deep discharge. Once the minimum level or maximum backup time is reached, the output is automatically disconnected to protect the battery.
