36V/48V to 19V 10A StepDown DC Converter A compact DCDC stepdown converter that accepts 36V or 48V DC input and delivers a regulated 19V DC output at up to 10A. Designed to make it simple to power 19V devices from highervoltage battery packs or DC systems without adding bulky inverters or multiple power supplies. Key benefits Direct conversion from 36V/48V to 19V at up to 10A, eliminating the need for additional adapters when using highervoltage DC sources. Simplifies mobile, vehicle, or batterypowered installations by providing a single stable 19V supply from common 36V/48V systems. Conserves space and reduces system complexity compared with using separate chargers or inverters. Protects connected equipment by providing a rated DC output for devices that require a 19V input. What this product solves Allows devices specified for 19V input to run from 36V or 48V battery systems without modification. Removes dependence on AC mains or large power converters for field, mobile, or backuppower deployments. Streamlines installations where a reliable 19V supply is needed across vehicles, renewableenergy systems, or industrial equipment. Key attributes Functionality: Stepdown (buck) DCDC conversion from 36V/48V input to fixed 19V output. Compatibility: Intended for use with 36V and 48V DC sources and devices that require 19V DC at up to 10A. Output performance: 19V DC, maximum current 10A (observe rated limits for continuous use). Use environment: Suitable for applications that require a stable 19V DC supply from highervoltage DC sources. Ease of connection: Designed for straightforward input and output wiring to standard DC power sources and loads. Applications and use cases Mobile and vehicle power: Power 19V laptops, routers, or network equipment directly from 36V/48V vehicle or marine battery systems. Surveillance and networking: Supply DVRs, NVRs, IP switchers, or routers that require 19V DC in offgrid or backuppower setups. Field and industrial equipment: Run small industrial control units, monitors, or test equipment that need 19V from highervoltage DC supplies. Installation and usage notes Confirm your source is a stable 36V or 48V DC supply and that the connected load does not exceed 10A. Use appropriate wiring, fusing, and mounting practices for the installation environment. Do not exceed the rated input range or output current to ensure reliable operation. This converter provides a practical, spacesaving solution for delivering a stable 19V DC supply from 36V or 48V systems, enabling easier integration of 19V equipment into mobile, batterybacked, or highervoltage DC installations.
