More Power, More Headroom, More System Value

The RACPRO1 family from RECOM combines high power density with practical power reserves, a slim form factor, and a system-oriented accessory concept for selective protection and redundancy. Unlike conventional standard power supplies designed only for nominal operation, RACPRO1 is consistently engineered for real industrial load profiles. Another clear advantage of the RACPRO1 family is its European origin: the products are Made in Europe, ensuring short supply chains, high manufacturing standards, and reliable quality. The combination of technical excellence and product design is further demonstrated by awards such as the Red Dot Award and the European Design Award 2025 in the Product Design category.

Efficiency, narrow width, and a wide input voltage range are key criteria when selecting modern DIN rail power supplies. However, in real industrial applications, another factor often determines operational reliability: how well a power supply handles dynamic loads, inrush current, and short-term overload conditions.

The RACPRO1-S series is specifically designed for this. The single-phase variants already cover 120W to 480W and combine a compact design with real power reserve. The 120W model requires only 28mm width, the 240W model 39mm, and the 480W model 52mm. At the same time, the series offers a power boost of up to 150% for 5 seconds, enabling reliable startup of inductive or capacitive loads. This allows RECOM to address not only the supply of control, communication, and sensor systems, but also applications with high inrush current or pronounced load transients.

Many DIN rail power supplies look convincing on paper but quickly reach their limits in real applications—whether due to temperature, load peaks, or limited installation space. RECOM specifically addresses these challenges. The RACPRO1-S series operates up to +60°C without derating and combines this with a wide input range of 85–277VAC. This reduces design risks and simplifies global deployment in machinery, building automation, energy systems, and infrastructure applications.

The official datasheets also reflect the clear focus on robust industrial use: the products are described as highly reliable DIN rail power supplies and are intended for industrial automation, building and home automation, datacom and telecom infrastructure, and energy. This makes RACPRO1 not just a compact power supply, but a robust power platform for professional systems.

A key aspect of modern power supply concepts is the system approach. The RACPRO1 family does not end with the AC/DC power supply—it is complemented by redundancy modules and electronic protection devices specifically designed for industrial availability and selective load distribution.

The RACPRO1-RD40 redundancy module supports 12V, 24V, and 48V systems, is only 43mm wide, and uses MOSFET-based isolation instead of traditional diodes. This reduces voltage drop and power loss, improving overall system efficiency. For applications with high availability requirements, this enables a clean n+1 architecture without unnecessary thermal disadvantages.

Equally important is the RACPRO1-4SP e-fuse series. It offers up to 10A per channel, 150% power boost for 5 seconds, sequential channel activation to reduce inrush current, and a prioritized shutdown behavior under overload conditions. Unlike simple protection concepts, energy distribution is actively managed: less critical loads are disconnected first, while essential functions remain powered as long as possible. For automation and control applications, this represents a significant gain in operational reliability.

A key differentiator of the RACPRO1-4SP series becomes evident in real fault scenarios. Even in the event of a short circuit or severe overload on one channel, the remaining channels remain stable, without being affected by voltage dips, ripple, or uncontrolled shutdowns. Even when the total power capacity is exceeded, the protection concept operates in a defined and predictable manner. Intelligent prioritization ensures that secondary channels are selectively shut down under overload conditions, while critical loads remain active for as long as possible.

Additional practical advantages include sequential channel startup to protect the input power supply, easy daisy-chain capability, and controlled startup behavior even with capacitive loads. For machine building, automation, and 24V distribution systems, this results in a significantly more robust and manageable protection concept. A space-saving version of the e-fuse in book-shape format for confined control cabinet applications will be released in the coming weeks.

In the industrial DIN rail power supply segment, RECOM’s solution is deliberately broad. In addition to the single-phase RACPRO1-S devices, the family also includes three-phase RACPRO1-T variants ranging from 240W to 960W. The 240W three-phase unit requires only 43mm width, while the 960W model measures 80mm. Here as well, compact dimensions, high power density, and boost capability are key features. For machine builders and control cabinet designers, this means a consistent platform concept—from compact auxiliary power supplies to high-performance main power systems.

In daily operations, handling is just as important as electrical performance. RECOM highlights the 25° push-in terminals of the RACPRO1 series, which enable fast, tool-free installation or quick replacement. Especially in control cabinet construction, series production, and service scenarios, this reduces wiring time and minimizes potential installation errors. The combination of compact geometry, good accessibility, and high power density ensures that even tight installation conditions can be managed effectively.

The evaluation of modern DIN-rail power supplies should not stop at efficiency, power dissipation, and heat generation. These criteria are important but do not fully capture the requirements of industrial power systems. This is exactly where RECOM demonstrates its strengths. The RACPRO1 family is not only slim, but also powerful, scalable, and system-capable. It addresses not only the need for reduced power loss, but above all the requirements of modern industrial systems in terms of availability, dynamic performance, and scalability.

Anyone who defines DIN rail power supplies solely by efficiency and width is only looking at part of the picture. Modern industrial applications demand more: dynamic power reserves, robust temperature performance, system availability, and modular expansion options.

Here comes the RECOM’s RACPRO1 family into play. The result is not just a standard power supply, but a well-designed power concept for professional applications—compact in the control cabinet, strong underload peaks, and consistently engineered for industrial robustness. Combined with European manufacturing and award-winning design—Made in Europe, recognized with the Red Dot Award and the European Design Award 2025 (Product Design)—the RACPRO1 family underscores its position as a technically and aesthetically leading solution for professional industrial applications.
