UPSI-2406R2DP2MB

Intelligent DC-UPS / DIN Rail / USB / RS485 / 144W / 24V 6A / Supercap / DC-DC / EDLC

Next-gen DC UPS solution “Made in Germany”:
Maintenance-free 24V / 6A backup power supply with Supercap technology, USB-C and RS485 Modbus interface

The UPSI-2406R2DP2MB represents the latest generation of intelligent DC UPS systems for DIN rail mounting – designed for maximum availability, maintenance-free operation, and exceptionally long service life. It reliably protects control and automation applications against power failures, voltage drops, or flicker.

Instead of conventional batteries, the compact 24VDC backup power supply uses high-performance double-layer capacitors (Supercaps/EDLC) that provide up to 500,000 charge and discharge cycles, ensuring completely maintenance-free operation. The extended operating temperature range of -20…+65 °C makes the UPSI-2406R2DP2MB ideal for demanding industrial environments.

With front-side USB-C and RS485 Modbus interfaces, the DC UPS can be seamlessly integrated into existing control systems and conveniently monitored via the included UPScom management software. Extended protection mechanisms and high immunity to surge and burst disturbances ensure additional operational reliability.

The compact UPSI-2406R2DP2MB in a robust DIN-rail housing is perfectly suited for long-term use in control cabinet applications and decentralized power systems. It ensures reliable backup of embedded IPCs, controllers, motor drives, sensors, as well as measurement, control, and safety equipment.

Increased Surge & Burst immunity and comprehensive protection functions

The 24V DC UPS offers high immunity against fast transients (burst) and surge voltages. It complies with standards EN 61000-4-4 and EN 61000-4-5, with test voltages of up to 2kV for burst tests and up to ±0.5kV (L–N) and ±1kV (L–PE, N–PE) for surge tests, each with test criterion A. This ensures reliable operation even in electromagnetically demanding environments.

In addition, the emergency power supply is equipped with extensive protection functions, including reverse polarity protection, short-circuit protection, and overcurrent protection. These features ensure maximum operational safety, extend the service life of connected devices, and minimize failure risks in critical applications.

Maintenance-free energy storage with long-life Supercaps

The UPSI-2406R2DP2MB uses state-of-the-art long-life Supercaps (ultracapacitors) as maintenance-free energy storage devices. These electro-physical double-layer capacitors (EDLC) are charged within a very short time, offer up to 500,000 charge and discharge cycles, and stand out with high power density, reliability, and maintenance-free operation. Unlike batteries, Supercaps do not undergo chemical aging – they achieve up to ten times the service life of lead-acid systems. The integrated Supercap energy storage is designed for an operating temperature range of -20…+65 °C and features an active cell balancing system for maximum efficiency in continuous industrial operation.

'Power Sharing' with intelligent input current control

The intelligent power sharing function on the 24VDC input enables efficient power distribution between the load and the Supercap charger. This allows the upstream AC/DC power supply to remain optimally sized, as the input power is automatically kept constant and dynamically distributed between output and charger as needed. At low output load, more energy flows into charging; at higher load, correspondingly less. This ensures sustainable reductions in both energy consumption and overall system costs.

UPS management software 'UPScom'
with intuitive user interface

The software 'UPScom' (freely available for download) allows the connected devices to be shut down and switched off in a controlled manner during a power failure in order to avoid data loss or damage. The responsive WEB UI is called up in a web browser to set and pre-program all parameters of the DC UPS system and for real-time monitoring with state-of-charge indicator. The adjustable parameters include, among other things, load sensor (mA), shutdown delay, maximum backup time, minimum charge capacity before system start, notifications by email.

Cross-platform technology

'UPScom' uses the new WebAssembly (WASM) architecture, which runs 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.

Secure Shutdown & Reboot function for IPC systems

In the event of a "power failure", the UPS signals the failure of the supply voltage via the integrated interfaces, 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 your own application-relevant processes. The integrated reboot function of the DC UPS automatically restarts the supplied IPC after the supply voltage returns, 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.

Email messenger service

'UPScom' can be used for various events such as loss of connection to the UPS, system shutdown or power failure. These preventative measures can reduce or eliminate downtime.
