Newmar 24-12-3 DC Converter, 17-32V to 12V

The Newmar 24-12-3 DC Converter takes 17-32V DC to a regulated 12V output at 3A, with 1% regulation and low ripple.

Three amps is a small output, sized for one instrument or a radio rather than a group of equipment. That is the right approach where a single 12V device sits on a 24V boat: a large converter would cost more and draw idle current for capacity never used.

Low ripple matters as much as the current rating on a converter feeding communication equipment. Ripple is the residual AC riding on the DC output, and a receiver hears it as noise even when the voltage reading looks perfect.

The 17 to 32V input covers a 24V system across its full charge and discharge range. Nominal output is 13.6V, internally adjustable from around 12.6V to 14.5V, with regulation within 1 percent under rated conditions. Explore more DC-DC converters and power supplies.
