36V48V to 19V 3A StepDown DC Converter provides a simple, reliable way to power 19V devices from 36V or 48V DC sources. It converts higher battery voltages down to a stable 19V output at up to 3A, enabling mobile and offgrid use of equipment that normally requires a dedicated 19V adapter. Key benefits Enables use of 19V equipment from 36V or 48V battery systems without changing the device or its charger. Provides a regulated 19V supply at up to 3A to keep connected devices stable under varying input conditions. Simplifies power setups in vehicles, ebikes, solar/battery systems, and industrial applications by removing the need for bulky adapters or multiple power supplies. Compact and durable design fits into mobile or spaceconstrained installations and is suited for field or workshop use. Key attributes Functionality: Stepdown (buck) DCDC conversion from 36V or 48V input to fixed 19V output at a maximum of 3A. Compatibility: Designed for devices that require a steady 19V DC supply and draw up to 3A. Suitable for many laptops, monitors, routers, and other 19V electronics when matched to connector and polarity requirements. Performance: Provides regulated 19V output at up to 3A to maintain stable operation of connected devices across expected input voltage ranges. Size and form factor: Compact footprint for easy integration into mobile, desktop, or enclosed power systems (verify physical dimensions with the specific unit before installation). Construction and reliability: Built for practical use in portable and stationary installations; verify environmental and mounting requirements for your application. Applications / use cases Mobile workstation or field laptop power: Power a 19V laptop or mobile workstation directly from a 36V or 48V battery pack (for example, ebike or vehicle battery) to run diagnostics, data logging, or office applications without AC mains. Offgrid or solar installations: Use the converter to supply 19V network devices, small displays, or other electronics from a solarcharged 36V/48V battery bank, reducing the need for extra inverters or adapters. Workshop and industrial equipment: Integrate into assembly, testing, or control systems where a reliable 19V DC rail is required from highervoltage battery or bus supplies. Practical notes Verify the device you intend to power accepts 19V and does not exceed 3A current draw. Confirm connector type and polarity before connecting to avoid damage to your device. Observe proper installation and cooling practices based on the operating environment to ensure consistent performance. Technical summary Input voltage: 36V or 48V DC Output voltage: 19V DC Maximum output current: 3A Conversion type: Stepdown (buck) DCDC converter This converter is a straightforward solution for powering 19V devices from 36V or 48V DC sources. Confirm connector compatibility and current requirements for your specific device before use.
