The Phoenix Contact MINI-DC-UPS/24DC/2 is a compact 24 V DC uninterruptible power supply designed to ensure continuous power delivery in industrial automation systems. By integrating a DC power supply and UPS into a single DIN-rail device, it provides a reliable 2 A output to protect PLCs, HMIs, industrial PCs, and communication equipment from voltage dips and short power interruptions. Its fast transition to battery operation helps prevent controller resets, data loss, and unexpected machine stoppages, making it well suited for control cabinets where stable operation is critical.
With configurable buffer times and support for external battery modules, the MINI-DC-UPS/24DC/2 allows backup duration to be precisely matched to application requirements. Intelligent, temperature-compensated battery charging improves safety and extends battery service life, while clear LED and relay signaling simplifies monitoring and diagnostics. These capabilities make the unit ideal for production lines, distributed automation systems, and infrastructure control panels that demand high availability, predictable behavior, and reduced downtime under unstable power conditions.

In automated production environments, even a brief power disturbance can interrupt PLC operation and halt synchronized machine processes. The MINI-DC-UPS/24DC/2 is installed to maintain uninterrupted 24 V DC power to controllers, I/O stations, and safety logic during voltage drops or short outages. Its rapid transition to buffered power keeps control programs active, preventing unexpected resets. Adjustable buffer durations allow systems to either ride through momentary failures or complete controlled shutdowns. This approach improves line stability, reduces material waste caused by sudden stops, and shortens recovery time after power is restored.
Industrial communication devices such as Ethernet switches, gateways, and fieldbus couplers are vulnerable to power loss and often require long restart times. The MINI-DC-UPS/24DC/2 is used to supply continuous DC power to these network components, ensuring communication remains active during unstable power conditions. By preventing network interruptions, it protects data exchange between machines, controllers, and monitoring systems. Clear status signaling enables maintenance personnel to quickly identify power-related events. This application is especially important in distributed systems where network downtime directly impacts process coordination and operational transparency.
Industrial PCs and operator panels frequently handle process data, configuration files, and production parameters that can be damaged by sudden shutdowns. The MINI-DC-UPS/24DC/2 provides a reliable power buffer that keeps these devices running through short outages or supports an orderly shutdown sequence. Stable output voltage and low electrical noise protect sensitive electronics, while intelligent charging helps preserve battery health. As a result, data integrity is maintained, unplanned maintenance is reduced, and operators can resume work immediately once normal power conditions return.
In applications such as water treatment facilities, pumping stations, or roadside control cabinets, power interruptions can affect safety and service continuity. The MINI-DC-UPS/24DC/2 is applied to back up essential control electronics, sensors, and communication units in these installations. By maintaining DC power during brief outages, it allows systems to continue operating or transition safely to predefined states. Its compact design, wide operating temperature range, and high reliability make it suitable for unattended or harsh environments where consistent control availability is essential.
