EN 50155 approved 40W DC/DC Power Converter with patented enhanced Hold-up Function

P-DUKE has announced another ultra-wide input voltage range DC/DC converter, the RED40U, to its 20W to 200W DC/DC converters with a 12:1 input voltage range. This DC/DC converter series provides high performance and reliability for any railway/ rolling stock and industrial application. The compact 2"x1" industrial standard package delivers up to 40W output power and features 8:1 and 12:1 ultra-wide input voltage ranges of 9-75VDC and 14-160VDC, which simplify the design of the system’s power stage. Using just one DC/DC converter model for various supply voltages (24, 28, 36, 48, 72, 96, 110VDC) in different regions avoids multiple input voltage models in the warehouse.

The patented enhanced Hold-Up Function is designed to simplify the design of supply interruptions and changeovers as per EN 50155. The BUS pin of the RED40U provides a stable and fixed charging voltage which allows the usage of just one Hold-Up capacitor for any input voltages and additionally, reduces the in-rush current during the start-up phase.
