[Introduction]：AM31-12W05V is an ultra-small switching power supply module, AC and DC dual-purpose, input voltage 85~264Vac/100~370Vdc, ultra-low ripple, ultra-low power consumption, high efficiency, safety isolation, high reliability and other advantages; It complies with IEC60950, EN60950, and UL60950 certification standards. There is no need to add EMI-related components to peripherals, which greatly reduces the user's design threshold; users do not need to consider stability, and the output can be stable even in extremely complex voltage environments.
