Board mount AC/DC converters are electronic components designed to convert alternating current (AC) from mains power into regulated direct current (DC) voltages that can be used to power electronic circuits directly on a printed circuit board (PCB). Unlike traditional power supplies that may be housed in separate enclosures, board mount converters are compact and designed for direct integration onto the board, reducing system size, simplifying assembly, and improving electrical performance by minimizing interconnections. They are available in a range of power ratings, input voltages, and output configurations to suit diverse applications.
