The 24V to 9V 4A power stepdown module is a compact DCDC buck converter that reduces a 24V DC input to a regulated 9V DC output, delivering up to 4 A to power 9V devices. Designed for projects and systems that require a 9V rail from a 24V source, it provides a reliable and straightforward solution without a separate 9V power supply. Key benefits Provides a stable 9V output from a 24V source, up to 4 A. Enables use of common 24V power supplies to power 9V devices, simplifying wiring and inventory. Boardlevel module with a compact footprint for easy integration into enclosures or projects. Simple input and output connections for quick prototyping and deployment. Reduces the number of required power supplies in a system by consolidating to a single source. Key attributes Functionality: DCDC buck converter (stepdown) from 24V to 9V. Input voltage: 24V DC. Output voltage: 9V DC. Maximum output current: 4 A. Maximum output power: 36 W (9V × 4A; actual delivered power may vary with efficiency). Form factor: compact boardlevel module suitable for tight spaces. Construction: boardlevel module based on a printed circuit board. Performance notes: Efficiency and thermal performance depend on load, input voltage, and wiring; ensure the input source can provide sufficient current. Technical specifications (summary) Input voltage: 24V DC Output voltage: 9V DC Maximum output current: 4 A Maximum output power: 36 W Form factor: compact boardlevel module Construction: PCBbased module Notes: Performance varies with load and conditions; verify that the input supply can handle the required current. Applications Powering 9V devices from a 24V power source in industrial control panels or automation projects. Providing a 9V rail for small 9V motors, controllers, or display modules in robotics or prototyping setups. Educational or hobbyist experiments that require converting a 24V supply to a 9V test bench source. Compatibility and installation tips Ensure the connected load does not exceed 4A to avoid overloading the module. Confirm the 24V source can provide the required current for both the load and the module's operation. Verify correct polarity when connecting input and output terminals and use secure, solid connections.
