Industrial cabinets rarely give engineers the mechanical freedom they want. Once a panel fills up, increasing power capacity usually means redesigning the enclosure or shifting other equipment, which is often not practical. Supplies that can deliver higher output without expanding the footprint therefore carry real value. RECOM’s RACPRO1-S240E series aims to support that need by offering a compact DIN rail format that maintains strong thermal behavior and usable headroom across a wide temperature range.
Stable Power Delivery In Space Constrained Installations
Many teams try to avoid adding fans because moving parts introduce their own maintenance cycles and can become a point of failure. A supply that can hold 240 watts on convection cooling alone therefore simplifies long term reliability planning. There is also more headroom than the nominal rating suggests. At moderate temperatures the supply can stretch toward 288 watts, and it still has enough thermal margin to handle a five second surge around 360 watts when a downstream load demands a brief kick of extra power. This helps during motor deceleration, startup events or other short transients that would otherwise force a larger unit.
AC Input Selection And Behavior With Back Feeding Loads
Different regions place different demands on line voltage, so the supply offers two selectable AC input windows that cover global operation. Once connected, the inrush stage is tuned to bring the unit onto the line gradually rather than with a sharp current spike. That approach reduces the chance of nuisance trips on upstream breakers. The outputs are available in 12, 24 and 48 volts, and the supply is built to tolerate return voltages produced by inductors or slowing motors, which gives designers more confidence when working with electromechanical loads. A DC OK signal is included for systems that monitor rail health.
Mechanical Design That Fits Narrow DIN Rail Spaces
A width of 39 millimeters gives the supply a small mechanical footprint, which is useful in cabinets where relays, terminals and control modules leave limited space. Mounting does not require tools, and the push in connectors simplify wiring during installation or field service. The unit weighs 625 grams and carries certifications for the safety and EMC standards commonly applied to industrial control, measurement and automation equipment.
Efficiency And Long Term Operation For Industrial Use
The series reaches efficiencies up to 93.5 percent, which helps keep internal temperatures stable and supports its lifetime expectation of 112,000 hours at 40 degrees Celsius. Lower heat generation also makes cabinet level thermal management easier when multiple supplies are stacked together. No load power stays under 0.8 watts, which is practical for equipment with tight standby power limits or energy requirements that constrain idle consumption.
For engineers, the takeaway is that the RACPRO1-S240E series offers a practical balance of power density, thermal stability and installation convenience. It provides added capability in cabinets where space and environmental limits usually impose strict design choices.
