200W AC-DC Power Supply with GaN Switching is 2.5-X SmallerDecember 12, 2019 by Paul Shepard
FiDUS Power has launched the model GDA200, a compact 200W desktop ac-dc power supply. The use of gallium nitride (GaN) rather than silicon semiconductor switches provides increased efficiency, reduced heat losses and operation a higher-frequencies, allowing the size of magnetics and other components to be reduced. The result is a 200W external desktop power supply claiming market leading 12.5W/In³ power density.
The FiDUS GDA200 is expected to fine use in portable equipment and instrumentation in markets including; high end audio, test and measurement, bench top and audio broadcast equipment.
The very small size, just 150 x 54 x 33mm (5.9 x 2.12 x 1.3”) may also reduce total system package size resulting in higher shipping and storage densities, especially when conventional silicon-based designs are about 2.5-times larger.
Mark Gibbons, Engineering Manager at FiDUS Power, comments: “The ultra-high power density and exceptionally small size of our new GDA200 external power supply gives designers of portable products a great deal more value for money and design flexibility. This is the first of a new family of ultra-compact external desk top products to be announced by FiDUS Power with the 300, 160 or 150 and finally GDA 120W series to follow early next year.”
The FiDUS GDA200 is available in class I or II (C14 and C8 inlet), with the C14 inlet model 11mm longer than the C8 model to accommodate the IEC input. It offers designers future proofing with the latest energy efficiency legislation; Department of Energy Level VI & Energy Related Products Tier 2, and latest general safety approval EN62368-1.
The units offer global approvals for use in Japan (PSE), China (CCC) and Taiwan (BSMI) as well as the Americas (UL) and Europe (CE). The units are suitable for use in ITE applications conforming to conducted and radiated emissions EN55032 level B.
The GDA200 range is reliable, cost competitive and has a FiDUS 5-year warranty. The units offer 192-200 watts of output power with output voltages available between 12- and 56-Vdc.
