AC-DC converters are an essential part in devices which rely on the mains power. These AC-DC converters have to withstand various transient spikes and voltage fluctuations. Therefore, a robust design is necessary. The RAC05-K/PD3/H from RECOM is a board-mounted 5W Class II AC/DC converter series. It is suitable for ‘fixed installations’ where higher levels of transients according to over-voltage category III are experienced, along with increased environmental pollution levels.
The converters are available with 5V, 12V or 15V single outputs and feature nominal input ratings of 100VAC to 277VAC, but the parts will withstand 480Vac without damage continuously. It includes enhanced clearances to meet OVCIII up to 5000m altitude, and rated for operation in ‘Pollution Degree 3’ environments. In these environments, the pollutants become conductive if condensation occurs.
The series is fully protected against short circuits and over-voltage. They feature a no-load consumption of less than 0.5W, and can operate up to 70 degrees Celsius. The parts are offered in a 2” x 1” x 1” high package.
