The AC20 40V to DC12V 8A power supply step down converter is a waterproof AC to DC stabilized module that converts a wide AC input range into a reliable 12V DC output. It is designed for use in outdoor or damp environments where a stable 12V supply is needed for 12V loads. Key benefits Stable 12V DC output up to 8A for reliable operation of 12V devices. Wide input range of 20 to 40V AC, reducing the need for precise input control and enabling flexibility in power sources. Waterproof module suitable for outdoor or wet locations, increasing durability and reducing weather related installation concerns. Step down conversion provides a clean, regulated voltage to sensitive equipment, helping to prevent voltage spikes and fluctuations. Compact, enclosed design supports easy integration into existing systems and simple mounting. Key attributes Functionality: AC input 20 40V AC, DC output 12V stabilized, maximum current 8A (approximate output power up to 96 W). Compatibility: Suitable for devices and circuits requiring a 12V DC supply within an 8A limit. Size and design: Compact waterproof module for easy installation and mounting. Enclosure/material: Waterproof module with a sealed enclosure suitable for use in wet environments. Performance: Delivers stabilized 12V DC with protection provided by the module's design for outdoor reliability. Applications and use cases Outdoor lighting systems that require a stable 12V power source from a wider AC supply, such as garden, porch, or façade lights. Outdoor or damp environment surveillance systems, including CCTV cameras and related equipment requiring a steady 12V supply. Weatherproof automation and sensor installations that operate at 12V, including environmental monitoring stations and remote control modules. Notes Ensure input voltage remains within the specified 20 40V AC range and the load does not exceed 8A to maintain stable operation. The module is designed to provide a stabilized 12V output for compatible 12V devices in wet or outdoor environments.
