The 24V(18 40V) to 13.8V 15A DC converter step down waterproof power module provides a stable 13.8V output from a wide DC input range. Designed for reliability in harsh or outdoor environments, it is suitable for powering 12V equipment and charging 12V batteries from 24V or other higher voltage sources. Key benefits Wide input voltage range enables operation from 18 to 40V DC, including common 24V systems. Delivers a steady 13.8V DC output at up to 15A, allowing reliable power for 12V devices and battery charging. Waterproof construction supports outdoor, marine, and wet location installations. Step down design converts higher voltage safely to a 13.8V supply, reducing voltage mismatch for 12V equipment. Simple integration as a dedicated power module in existing 24V electrical systems, with no need for external regulation. Key attributes Functionality: DC converter step down from 18 40V DC input to a fixed 13.8V DC output. Compatibility: Suitable for 24V systems and other sources within the 18 40V range; provides 13.8V at up to 15A. Output capability: Maximum output current 15A; maximum potential output power up to 207W (13.8V × 15A). Durability: Waterproof power module designed for use in environments where moisture exposure is possible. Form factor: Module designed for integration into electrical installations, vehicles, boats, and similar applications that require a robust 13.8V supply. Applications: Automotive and commercial vehicles: Convert a 24V or higher DC source to a stable 13.8V for lighting, radios, sensors, and other 12V accessories, or to maintain 12V battery banks. Marine and outdoor installations: Use in boats or exposed equipment where a reliable 13.8V supply is needed from a 24V electrical system or other wide range DC sources. Off grid and renewable setups: Supply a steady 13.8V to 12V loads or battery charging from variable input sources that fall within 18 40V DC, such as certain solar or wind configurations. Notes: This module converts DC voltage only and is designed to deliver up to 15A at 13.8V. Ensure that the total load does not exceed the 15A rating and that the input source can supply the required current. In summary, this 24V(18 40V) to 13.8V 15A DC converter step down waterproof power module offers a reliable, water resistant solution for obtaining a stable 13.8V power supply from a wide 18 40V DC input, with up to 15A of current for 12V devices and battery charging in demanding environments.
