UPSI-2415DP2

Intelligent DC UPS / DIN Rail / USB / ModBus / 360W / 24VDC 15A / Supercaps / DC-DC / EDLC

Next-gen 15A DC UPS solution ‘Made in Germany’: Supercap technology, fast charging process and USB-C / RS485 Modbus interface

The UPSI-2415DP2 is the latest generation of intelligent DC UPS systems for DIN rail mounting – designed for maximum operational reliability and optimal data communication. It ensures reliable protection of control and automation applications in the event of a power failure, voltage dip or flicker.

Instead of conventional batteries, the compact 24VDC emergency power supply relies on powerful double-layer capacitors (EDLC), known as supercaps, which enable up to 500,000 charge and discharge cycles and can therefore be operated completely maintenance-free. Thanks to its extended operating temperature range of -20…+65°C, the UPSI-2415DP2 is particularly suitable for demanding industrial applications.

The DC UPS can be easily integrated into existing control systems via the front-mounted USB-C and RS485 Modbus interfaces and conveniently monitored using the included UPScom management software. Extended protection mechanisms ensure additional operational reliability and increased surge & burst immunity.

The compact UPSI-2415DP2 DC UPS in a robust DIN rail housing is ideal for long-term use in control cabinet applications and decentralised power supply solutions. It ensures the protection of embedded IPCs, controllers, motor drives, sensors, and measurement, control and safety systems.

High intrinsic safety and comprehensive protection functions

The robust, high-quality DC UPS has intrinsically safe charging and control electronics with redundancy in case of failure. The entire charging and discharging process is monitored and controlled by the battery management system (BMS).

In addition, the 24V DC UPS is characterised by its high resistance to fast transients (bursts) and surge voltages. It meets the requirements of standards EN 61000-4-4 and EN 61000-4-5 with test voltages of up to 2 kV for burst tests and up to ±1 kV (L–N) and ±2 kV (L–PE, N–PE) for surge voltage loads, in each case according to test criterion A. This ensures that the system operates reliably even under demanding electromagnetic conditions.

In addition, the 24V emergency power supply is equipped with a comprehensive package of protective functions, including reverse polarity, short-circuit and overcurrent protection. This ensures maximum operational reliability, a long service life and minimised risk of failure in critical applications.

Fast charging thanks to optimised charging process

The UPSI-2415DP2 uses state-of-the-art long-life supercapacitors (ultracapacitors) as maintenance-free energy storage devices. These electrophysically operating double-layer capacitors (EDLC) can be charged in a very short time, offer up to 500,000 charge and discharge cycles and are characterised by high power density, reliability and maintenance-free operation. The newly developed and optimised charging process also significantly reduces charging time and enables rapid availability of the UPS. In addition to monitoring and safety functions, the battery management system (BMS) also performs cell balancing: in supercap systems, different cell voltages and capacities can occur, which affect service life. Cell balancing compensates for these differences, ensures a uniform voltage and capacity level, and thus increases both the performance and service life of the supercap energy storage system.

Intelligent power sharing thanks to input current detection

Intelligent power sharing at the 24VDC input enables efficient power distribution between the load and the supercapacitor charger. This means that the upstream AC/DC power supply does not need to be oversized, as the input power is automatically kept constant and dynamically distributed between the output and the charger as required. At low output loads, more energy flows into the charging process – at higher loads, correspondingly less. This sustainably reduces energy consumption and 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.
