24V to 13.8V 10A StepDown DCDC Converter Overview A purposebuilt DCDC stepdown converter that accepts a 24V DC input and provides a regulated 13.8V DC output at up to 10A continuous current. Designed to let equipment and accessories that require a 13.8V supply run reliably from 24V vehicle or system power rails. Key benefits Provides a stable, nominal 13.8V output from a 24V source so 13.8V devices can be used without modifying the vehicle or system power architecture. Solves the compatibility gap between 24V power systems and 13.8V electronics (radios, chargers, control modules), eliminating the need for separate batteries or converters for each device. Compact, practical solution for retrofits and installations where a reliable 13.8V supply is required from a 24V bus. What makes this unit useful Fixed 13.8V output: supplies devices that expect the industry standard 13.8V DC voltage for charging and operation. 10A continuous current capability: supports moderate loads such as communications equipment, small chargers, instrumentation, and control circuits. Stepdown (buck) conversion: efficient conversion method that reduces excess heat compared with linear regulation when dropping from 24V to 13.8V. Key attributes Functionality: Converts 24V DC input to a regulated 13.8V DC output. Designed for continuous use up to 10A load. Compatibility: Intended for nominal 24V systems and equipment that require a 13.8V supply. Typical applications include commercial vehicles, industrial machines, mobile workstations, and stationary 24V power systems that need a 13.8V branch. Size and installation: Compact form factor suitable for installation in confined equipment bays and vehicle compartments. Mounting and connection should follow standard electrical practices. Material and construction: Built for practical use in equipment and vehicle installations; constructed to withstand normal operating environments. Follow recommended mounting, ventilation, and protection practices for reliable operation. Performance: Regulated 13.8V output at up to 10A continuous current. Designed to maintain the output voltage under typical load conditions encountered in 13.8V devices. Use cases Mobile communications: Power 13.8V transceivers and mobile radio equipment from a 24V truck or bus electrical system without altering the radio or vehicle wiring. Battery charging and maintenance: Provide a 13.8V float/charge supply for 12V battery banks from a 24V power source to maintain batteries in vehicle or stationary applications. Electronics and control systems: Power 13.8V control modules, instrumentation, and small accessories in industrial and transportation equipment where the main supply is 24V. Installation and operation notes Intended for use on nominal 24V DC power systems. Verify system voltage and ensure correct polarity before connection. Rated for continuous output up to 10A; ensure the connected load does not exceed this rating. Provide adequate ventilation and mounting support to ensure reliable thermal performance during continuous operation. Follow applicable wiring standards and protective device (fuse/breaker) recommendations for the installation to protect wiring and connected equipment. Technical summary Input: 24V DC (nominal) Output: 13.8V DC (regulated) Maximum output current: 10A continuous Conversion type: Stepdown (buck) DCDC converter This unit is a straightforward solution when you need to run 13.8V equipment from a 24V source with a regulated supply and up to 10A of current.
