AC/DC power modules feature the widest input range available

RECOM has pushed the boundaries of AC/DC performance with a miniature 15W part that operates over an astonishingly wide input range of 18-264VAC or 18-375VDC. The board-mount RAC15-K/WI features a compact 1.5” x 2” (40 mm x 52.5 mm) footprint with an industry-standard pinout or optional flying wires, supplying a range of fully regulated output voltages from 5V to 54V DC.

Particularly high operating efficiency allows a full rating of 15W output, commonly above 48VAC input and up to 60C ambient, depending on output voltage variant. Between 18VAC and 48VAC, and at high ambient temperatures with convection cooling to 85C, useful power levels are still available.

The ultra-wide input range of the device does not compromise on performance; however, the Class II parts meet reinforced isolation standards according to UL/IEC/EN/CAN-CSA 62368-1 for audio/video and IT equipment and IEC/EN 60335-1 for household appliances. ‘Class B’ EMC levels and eco-design requirements for standby and no-load losses are met. Outputs are classed ‘Limited Power Source’ and are fully protected against shorts and overvoltage, while the AC input is rated for Over-Voltage Category III operation up to 3000m.

“These highly versatile AC/DCs suit applications where the input can vary widely or where it is advantageous to fit just one part to cover several nominal inputs,” comments Michael Schrutka, MSc AC/DC product manager of RECOM. “Along with our mechanically identical RAC15-K/480, just two 15W-rated RECOM parts can now cover nominal inputs between 18VAC and 480VAC.”

Parts include a three-year warranty.
