This DCDC stepdown module converts a higher DC input in the range of 22 to 40 V to a steady 19 V output, delivering up to 40 A. It is designed for applications that require a reliable 19 V supply sourced from 24 V or higher systems. The module provides a constant voltage output suitable for devices that operate at 19 V. Key benefits Stable 19 V output from a wide input range (22 to 40 V), enabling flexible use with multiple power sources. current capability up to 40 A to power demanding devices such as laptops, displays, and other 19 V equipment. Constant voltage regulation for predictable performance as load changes. Compact module form factor for easy integration into panels, enclosures, or custom power systems. Simple integration with standard DC power sources without the need for separate voltage adapters. Key attributes Functionality: DCDC stepdown converter with a fixed 19 V output and a wide input range of 22–40 V DC. Maximum output current is 40 A. Provides a constant voltage output. Compatibility: Suitable for devices that require 19 V input, including laptops, monitors, and other 19 V powered equipment. Works with 24 V systems and other sources within the 22–40 V range. Size and form factor: Compact module design intended for straightforward integration into existing power designs, control panels, or equipment enclosures. Construction and materials: Encased DCDC module designed for electronic applications. Built to deliver reliable performance in a compact package (specific dimensions and materials not specified here). Performance: Capable of delivering up to 40 A continuous output with stable 19 V regulation across the specified input range. Use cases Laptop or portable workstation power: Convert a 24 V or higher supply in a workshop or data center environment to a stable 19 V for laptops and 19 V powered devices. 19 V peripherals from solar or battery systems: Use in solar or batterypowered installations to supply a fixed 19 V rail for monitors, thin clients, or other 19 V equipment. Robotics and embedded projects: Provide a reliable 19 V power source for embedded boards, sensors, or controllers in a robotics or automation setup powered by a 22–40 V supply. Notes Input voltage must remain within 22–40 V DC to maintain the specified output. Output is 19 V with a constant voltage characteristic suitable for equipment designed for 19 V operation. Specific dimensions and enclosure material are not provided here; the module is described as a compact, integrationfriendly DCDC converter suitable for adding to power systems or enclosures.
