Seven different power-range classifications

With a large range of designs available, we classify our DC-DC converters into seven different groups based on their power usage: Please click a link below to see a full listing of our standard DC-DC converter power supplies.

0.5 to 3 Watt More than 20 series options in this category, built with single or dual output. Feature variations include internal SMD construction, continuous short-circuit protection, reinforced insulation, high-performance pi input filters, low noise, epoxy encapsulation, or no minimum load requirements. The SWU2/MHIA and TWB3/MHIA5 series are recommended for medical applications.

5 to 12 Watt Most of these converter series are available with single and dual output, while some have 2:1 or 4:1 wide input ranges. Built-in features include continuous short-circuit protection, over-voltage protection, fixed switching frequency, miniature packaging for tight spaces, six-sided shielding, or low output noise. Several series are useful for medical applications, including the TWA6/MHIA and the TWB6/MHIA5.

15 to 30 Watt This category includes more than 20 series of converters, most of which have single and dual output, a few with triple output. Features include fixed switching frequency, short-circuit or over-voltage protection, internal input fuses, six-sided metal shielding, epoxy encapsulation, and no minimum load requirements. The LWA15 series is ideal for medical applications, with several others recommended for the rail industry, like the DMWB30 series.
