With the advancement of electronic technology, compared with the traditional scalpels and procedures used during surgeries, electrical equipment has replaced non-electrical surgical equipment, such as da Vinci minimal invasive surgery, high-frequency electrosurgery, endoscopic electric cutters, shock wave lithotripter…etc. All types of electronic medical equipment require the DC voltage of the power supply to drive, and MEAN WELL’s enclosed type MSP/RPS-C series, or modular NMP series, PCB type MFM/MPM/RPS series, etc., can all provide a variety of DC output voltage options. The DC-DC module MDS/MDD series can be incorporated to achieve ultra-low leakage current <10μA and improve system EMI performance. In addition, portable instruments can also be powered by external GSM/GEM series adapters.
