The Autec Power Systems WM-M020A-059-A-USB is a medical-grade AC/DC power adapter from the WM-M020A series, delivering up to 17.7W of power. This wall-mount adapter accepts a universal input voltage range of 100-240Vac and features a regulated 5.9V output at 3A. It is designed to meet stringent medical standards, including IEC/EN/ANSI/AAMI ES60601-1 (edition 3.1) and EMC compliance to IEC60601-1-2 (edition 4.0), with 2 x MOPP means of protection.
Key technical specifications include Level VI efficiency, low ripple noise (2% Vp-p Max.), and a hold-up time of 10mS. Protection features include short circuit, over voltage, and over current protection, along with an internal primary current fuse and inrush limiting. The adapter operates within a temperature range of 0°C to +40°C and utilizes natural convection cooling. It is available with US, EU, and UK plug types.
This series is noted as 'Not Recommended for New Design' with a recommended replacement model WM-M024A. Parts are expected to reach end of life by the end of Q3, 2020.
