A common difficulty in modern industrial control cabinets is finding room for higher power budgets without giving up thermal headroom or reshaping the panel layout. Power demands continue to rise as more sensing, connectivity, and processing hardware moves to the edge, yet the enclosure itself stays the same size. This is where RECOM’s new RACPRO1-S480 becomes relevant. It gives engineers a way to increase available power without claiming extra space, and it does so in conditions where forced airflow is not guaranteed.
High Power in a Narrow 52mm Footprint
The supply delivers 480W under convection cooling from minus 40°C to plus 60°C, which reflects how many real cabinets operate once installed. One detail worth noting is that the output can climb to 576W at temperatures up to 45°C, with short bursts up to 720W for five seconds. In practice, that means designers can stay within a compact footprint without stepping up to a larger unit just to cover brief inrush or motor deceleration events. The 52mm width also helps when mounting alongside breakers, PLC modules, and other control equipment that compete for the same DIN rail space.
Electrical Behavior Suited to Mixed Industrial Loads
Adjustable 24V and 48V rails keep the device usable across a wide range of installations, and the DC-OK signal provides a simple way to track system status. When motors or other inductive loads feed energy back into the rail, it can create short-lived voltage rises that unsettle a supply. The RACPRO1-S480 is built to stay stable during those events, tolerating more than 35V on the 24V output and 63V on the 48V version without dropping out. Engineers can select constant current or parallel mode depending on whether the design calls for controlled current limiting or load sharing. The input accepts universal single-phase AC through active PFC and inrush limiting, or it can run from 88V to 370VDC in systems that rely on high-voltage DC distribution.
Reliability and Integration Considerations
Long-term reliability is usually dictated by how hot a supply runs rather than any single specification, so the focus on keeping losses low matters here. At 40°C, the expected operating life sits around 98,000 hours, which gives engineers room to plan maintenance cycles with confidence. The 780g unit drops into place without tools and the 25° push-in connectors cut down wiring time when cabinet depth is limited. Emissions and immunity fall within EN 61000-6-4 Class B and EN 61000-6-2 requirements, and the IEC, EN, UL, and CSA 61010 approvals simplify deployment across different regions.
Positioning for the Next Wave of Industrial Builds
As automation systems grow denser and more distributed, power supplies have to offer higher output in the same physical space while keeping thermals predictable. The RACPRO1-S480 fits that shift by holding steady under transient loads and maintaining performance in convection-cooled environments. For engineers, the takeaway is a supply that supports higher power density without compromising stability or compliance.
