WM-M020A-180-D-USB-M

The Autec Power Systems WM-M020A-180-D-USB-M is a medical grade wall mount AC-DC adapter delivering 18V DC at 1.11A with a maximum output power of 20W. It accepts a universal input of 100-240Vac at 50-60Hz, making it suitable for global use. The adapter complies with medical safety standards IEC/EN/ANSI/AAMI ES60601-1 (edition 3.1) and features 2xMOPP (Means of Patient Protection) for enhanced isolation.

Electrical performance includes a typical load regulation of ±5% and ripple of 2% Vp-p maximum at full load. Transient response is 0.5ms for a 50% load change, and hold-up time is 10ms at full load. Protection features include internal primary current fuse, inrush limiting, short circuit protection, over voltage protection, and over current protection.

Efficiency meets Energy Star Level VI, ErP Stage 2, and is NRCan & GEMS certified. The adapter is approved to UL/cUL/CE standards and complies with EMI EN55011 Class B, harmonic current EN61000-3-2/3, and EMS immunity IEC60601-1-2:2014 (edition 4.0). Dielectric withstand is 4000Vac between primary and secondary, with leakage current less than 100µA (optional less than 10µA).
