If a PCB board is not available or a power supply has to be fitted off-board because of a lack of space, RECOM offers AC/DC power supplies with wired terminations. Products are available up to 30W rating with a selection of output voltages from 3.3V to 48V. Inputs are universal AC mains with some parts rated to 305VAC for 277VAC nominal systems (RAC03-ER/277 and RAC05-K/277/W). All parts are dust and moisture sealed with some IP68-rated (RACM16E-K/277/W and RACM30-K/277/W). Products such as the RAC03 are circular in format for fitting into standard electrical wall boxes with typical applications in building automation and IIoT. Constant current LED drivers are also available from 3W to 7.4W in the RACD03/04/07 series.
