The 24V(18 40V) to 13.8V 10A power converter car regulator DC DC DC buck module provides a stable 13.8V DC output from a wide input range of 18 to 40V. Designed for automotive and other DC power applications, it delivers up to 10A of continuous current to power 13.8V devices reliably from higher voltage sources. Key benefits Regulated 13.8V output from a wide input range (18 40V DC), suitable for 24V vehicle systems and other DC sources. current capability up to 10A to run multiple devices or power demanding loads. Efficient DC DC buck operation converts higher input voltage to a steady 13.8V, helping protect connected equipment from voltage fluctuations. Compact module form factor that supports easy integration into vehicles, equipment enclosures, or DIY power projects. Simple wiring with standard DC connections for straightforward installation and operation. Key attributes Functionality: DC DC buck regulator that steps down input voltage to a fixed 13.8V output. Compatibility: Input DC range 18 40V; output fixed at 13.8V; maximum current 10A. Size and form: Compact module designed for practical in vehicle and DC regulation applications. Performance: Delivers a regulated 13.8V output at up to 10A, suitable for typical 13.8V devices and systems. Use cases Automotive power supply: In 24V trucks or buses, power 13.8V devices such as car radios, dash cameras, GPS units, and other 13.8V electronics from the vehicle electrical system. Higher voltage source to 13.8V loads: Use in workshops, solar or other DC systems where input may range from 18 to 40V to deliver a stable 13.8V supply for testing rigs, chargers, or instrumentation. Bench and field testing: Provide a reliable 13.8V source from variable DC supplies during evaluation of 13.8V electronics or during portable testing setups. Usage notes Connect the input to a DC source within 18 40V and the load to the 13.8V output. Do not exceed the 10A maximum continuous current to maintain proper operation and avoid overheating. Ensure adequate airflow around the module during current or extended use applications.
