Tiny 300W single output power supply qualifies for medical systems

November 16, 2020  Stephen Law

VOX POWER VCCS300M compact, conduction cooled, single output power supply is suitable for medical systems applications, delivering 95% efficiency and a highly reliable 1.1 FPMH. Product measures 4 x 2 x 1.61inches with power densities exceeding 23W/in³ and weighs 310g. Unit delivers 300W of silent, fanless power and, where the application or environment demands. Firm has also designed these units to be cooled by convection or forced air. Power solutions of 300W, 600W, 900W and beyond can be achieved by using the onboard droop current share function, which allows end users to scale up or down depending on their power requirements. Input voltage range is 85 to 264VAac (0.99 power factor) and output voltages are set initially at 12, 24 and 48Vdc with in-between voltages up to 58Vdc available on request. Figures for load and line regulation as well as ripple and noise are excellent while no load power consumption is below 1W.
