AC20 40V to DC12V 12A power supply step down converter is a waterproof module that converts AC input in the 20 to 40 volt range into a stabilized 12 volt DC output. This design provides reliable, continuous power for 12V loads in outdoor or damp environments and delivers up to 12A of current to support multiple devices from a single input source. Key benefits Stable 12V DC output from a wide AC input range of 20 40V AC, helping to accommodate various power sources without a separate transformer. current capability up to 12A, enabling multiple 12V devices to run from one unit. Waterproof module construction, suitable for outdoor installation and exposure to moisture. Module style for easy integration into panels, enclosures, or control boxes. Simplified power solution by consolidating AC to DC conversion in a single, compact unit. Stabilized output helps protect connected equipment from voltage fluctuations within the rated input range. Key attributes Functionality: AC to DC step down conversion with stabilized 12V DC output. Output: 12V DC, maximum 12A current. Input: AC supply in the 20 40V range. Performance: Stabilized output suitable for loads that require consistent voltage under varying input conditions. Compatibility: Designed to power 12V devices from an AC source within the specified range. Form factor: Waterproof module designed for straightforward mounting in enclosures or panels. Durability: Waterproof design intended for use in outdoor or damp environments without additional enclosure requirements. Applications Outdoor 12V lighting and illuminated signs powered from an AC source in the 20 40V range. Weatherproof powering of 12V CCTV cameras, sensors, or other equipment housed in outdoor enclosures. 12V DC devices such as small pumps, fans, or control electronics in gardens, farms, or industrial outdoor setups where a waterproof power solution is advantageous. Notes Ensure the AC input source can supply the required current for the connected 12V loads within the 12A rating. Provide appropriate mounting and enclosure considerations to maintain the waterproof performance of the module in its operating environment.
