This waterproof module is a AC to DC stabilized power supply that performs a stepdown from 20 40 V AC input to a regulated 5 V DC output with a current capability up to 12 A. It is designed as a compact module to power 5 V devices in outdoor or moistureprone environments where a reliable, shielded supply is required. Key benefits Reliable 5 V DC output: Provides a stabilized 5 V supply suitable for many 5 V electronic devices and systems. Wide input compatibility: Accepts AC input in the 20 40 V range, offering flexibility with various power sources. current capability: Delivers up to 12 A, enabling power for multiple devices or higher current loads at 5 V. Waterproof module design: Built to resist exposure to moisture, making it suitable for outdoor or damp environments. Simplified integration: Designed as a compact module for easy incorporation into existing assemblies or projects. Stable performance under load: Output remains regulated and steady to support sensitive electronics. Key attributes Function: AC to DC stabilized stepdown converter in a waterproof module form Input: AC 20 40 V Output: DC 5 V Current capability: Up to 12 A Regulation: Stabilized DC output Construction: Waterproof module for use in challenging environments Type: Power supply / stepdown converter Applications and use cases Outdoor lighting and signage: Convert higher voltage AC sources to a stable 5 V supply for LED strips, controllers, or small lighting controllers in exterior installations. Outdoor IoT devices and sensors: Power weather stations, cameras, or environmental sensors that require a 5 V regulated supply from a damp or exposed installation. Robotic and automation projects in moist environments: Provide a reliable 5 V power source for controllers, microprocessors, or peripheral modules in garages, workshops, or greenhouses. Usage notes Confirm device voltage and current requirements match the 5 V, up to 12 A supply capabilities. Ensure proper mounting and wiring to maintain the waterproof performance and electrical integrity. Verify input compatibility with available AC sources within the 20 40 V range before installation. This description aligns with the product's model and features as a AC20 40Vto DC5V 12A power supply stepdown converter and its waterproof module design, delivering a stabilized 5 V DC output from a wide AC input range while supporting current in adverse environments.
