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: 38.225.223mm;
- 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.
Application scenarios
- Power Supply System of Charging Pile；
- Intelligent home and Industrial sensors, etc.；
- Internal power supply system of security alarm；
- Industrial control；
- MCU motherboard, toys；
- Supply LED driving Lamp belt with Power；
- Intelligent street lamp；
- Intelligent switch, socket；

Notes
- Operating this module requires certain professional skills, prohibit non-professionals operate onit!
- Before using it, you must study knowledge of safe use.
- prohibit human body contact with L and N power lines after electrification to prevent accidents caused by electric shock. Recommend input front-end to Increase isolation.
- The maximum input voltage shall not exceed 250 Vac, otherwise may occur permanent damage.
- In daily maintenance, the input power should be disconnected to prevent from electric
