Product introduction
Brief introduction
AM11-12W05V is a low-power AC-DC step-down power supply module with an input voltage of 85~264Vac/100~370Vdc. This series of products are widely used consumer electronics, industrial control equipment, instrumentation, smart home and so on for its advantages such as ultra-low ripple, ultra-low power consumption, high efficiency, safe isolation and high reliability. The user does not need to consider stability because the output can be stabilized even in a complex voltage environment.
Product features
- Ultra-low ripple: full load ripple is less than 100mV;
- Ultra-small size: 38.2*25.2*23mm;
- Input voltage: universal voltage of 85 ~ 264Vac/100~370Vdc;
- Protection measures: over-voltage protection, over-current protection, short-circuit protection, over-temperature protection;
- High-quality scheme: greatly improve its work efficiency, with a maximum efficiency of 86.2%;
- AM11 series is aimed at economical ultra-low cost.
