CUI Inc GaN Adapters provide 120W to 300W continuous power, a compact size, and AC inlets. The use of GaN as a transistor increases efficiency, reduces the form factor, and extends the operating temperature range when used in switching applications. These adapters from CUI Inc include the SDI120G-U, SDI200G-U, SDI200G-UD, SDI300G-U, SDI300G-UR, SDM300G-U, and SDM300G-UR series.
