White Paper Overview

Today’s automated assembly and production lines increasingly employ smart control systems, artificial intelligence (AI), and advanced robotics to push productivity to previously unattainable levels. Taking advantage of these technologies demands a steady flow of power to keep operations running smoothly and reliably.

The RACPRO1 family of AC/DC DIN rail power supplies is designed to address the unique requirements of today’s advanced industrial automation applications, many of which operate in extreme environments. These include outdoor industrial installations such as traffic control systems, security systems, and parking garages where equipment is exposed to rain, dust, extreme temperatures, and humidity. Also included are factory environments, such as steel mills, foundries, and glass manufacturing plants with high ambient temperatures and airborne particulates, as well as food and beverage processing facilities requiring washdowns and chemical resistance for enhanced durability.

The RACPRO1 series of industrial DIN rail AC/DC power supplies is compact, efficient, and includes single-phase input versions rated up to 480W and three-phase versions rated up to 960W. Additionally, the REDIIN series offers single-phase universal AC inputs and outputs rated up to 480W for cost-sensitive applications, without compromising performance in demanding industrial environments. The new REFIN series is super-slim and offered in the ‘step-shape’ format with up to 90W continuous rating. To complement these products, four-channel resettable e-Fuses are available in the DIN rail format rated up to 10A, as well as soon-to-be-announced redundancy diode modules.

Features & Performance

With versions rated at 120W, 240W and 480W, the RACPRO1-S universal single-phase DIN rail AC/DC power supplies are just 28mm, 39mm and 52mm wide respectively. Adjustable output voltages are available at 12V, 24V and 48V for the 120W and 240W versions, and 24V and 48V for the 480W version. All parts support 150% power for 5s to handle surge loads and feature high return voltage immunity. Full power can be delivered up to +60°C for all parts under convection-only cooling, while higher temperatures can be withstood with derating.

Reliability and lifetime figures are high, supported by impressive efficiency of up to 95%.

Installation & Usability

The push-in terminals feature a unique ergonomic design and a 25° angle for easy, tool-free operation. These maintenance-free terminals, along with the thoughtfully designed DIN rail mounting clips, allow for quick installation and removal also without the need for tools.

Durability & Environmental Suitability

With surge immunity up to 4kV at the input and reverse voltage protection over 35V at the output, these devices are suited for demanding environments. Their extended temperature range of -40°C to +70°C makes them ideal for harsh industrial settings and outdoor applications, especially in renewable energy.
