DIN-Rail Modular DC-UPS Series
Compact, high-efficiency DIN-rail DC-UPS controllers with active power management, dry contact relay alarms, and optimized trickle/fast charging curves for 24V/48V automation systems.
View Technical DetailsIn high-density smart factories, automated logistics, and continuous process plants, brief power sags (voltage dips) cause costly PLC resets, corrupt IPC drive data, and force unscheduled downtime. Traditional monolithic AC-UPS systems are no longer optimal for modern cabinet architectures.
Modern industrial control cabinets operate predominantly on 24V DC or 48V DC busbars. Inserting a conventional double-conversion AC-UPS requires converting AC grid mains to DC, converting DC to AC within the UPS inverter, and then utilizing an AC/DC switch mode power supply inside the control panel to feed 24V DC components. This triple-conversion sequence degrades efficiency to under 75%, increases heat accumulation, and creates single points of failure.
A Modular DC-UPS Power Supply eliminates redundant AC/DC and DC/AC conversion stages. It directly supplies pristine, regulated 24V or 48V DC power while charging an integrated energy storage unit (Ultracapacitors, LiFePO4, or Lead-Acid). When mains power experiences a voltage brownout or sudden outage, the DC-UPS transitions to battery or capacitor back-up with microsecond switchover speeds, providing uninterrupted power continuity to critical PLCs, sensors, communication nodes, and servo actuators.
From ultra-compact DIN-rail modules for sensor back-up to high-power 105 kW rack-mounted DC buffer systems, CAMTEC provides engineered solutions tailored for high-availability environments.

As global manufacturing shifts toward Industry 4.0, autonomous mobile robots (AMRs), automated guided vehicles (AGVs), and smart DC microgrids, global procurement leaders are re-evaluating their power architecture strategies. Four dominant trends are defining the future of industrial procurement:
Next-generation DC power backup systems are moving beyond basic battery charging to become active power management nodes. CAMTEC stays at the forefront of power electronic design by embedding core technological advancements into every product platform.
By leveraging Silicon Carbide (SiC) and Gallium Nitride (GaN) switching components, CAMTEC Modular DC-UPS units achieve ultra-low thermal dissipation, exceeding 97% efficiency while dramatically shrinking the mechanical volume of the power modules.
Traditional diode-based redundancy modules introduce forward voltage drops and energy loss. CAMTEC integrates active wearless MosFET decoupling topologies (as seen in our UMS series) to provide seamless N+1 redundancy with zero power loss and infinite switching life cycles.
To maximize battery life and prevent thermal runaway, CAMTEC charging rectifiers feature micro-controller-driven 3-stage charging curves (I-U-U characteristics) with integrated ambient temperature sensor feedback and automatic battery health testing.
Choosing a power back-up supplier is a strategic decision that directly impacts machine reliability, brand reputation, and global service costs. CAMTEC Power Supplies GmbH brings decades of specialized power electronics expertise to every project.
