A compact, reliable stepdown DCDC converter that converts 24V DC input to a regulated 13.8V DC output at up to 40A continuous current. Designed to power 13.8V equipment directly from 24V vehicle, industrial, or solar systems, this converter provides a straightforward way to run 12Vclass electronics and charge 12V battery systems where only a 24V source is available. Key benefits Provides a stable 13.8V output from a 24V supply, eliminating the need for separate 12V power sources or complex wiring changes. Supports current loads up to 40A, enabling operation of radios, amplifiers, chargers, heaters, and other 13.8V devices without multiple converters. Simplifies system design and installation in 24V platforms by delivering a single regulated output that matches common 12V system requirements. What it does and why you need it Converts 24V DC to a regulated 13.8V DC output capable of supplying up to 40A continuous current, so devices designed for 13.8V operation run reliably from 24V sources. Useful wherever 24V systems must power 13.8V equipment: fleet trucks, marine and RV systems with dualbattery architectures, industrial machinery, telecom shelters, and offgrid or backup power installations. Reduces inventory and troubleshooting by standardizing power for 13.8V devices across different platforms. Key attributes Functionality: Stepdown (buck) DCDC conversion from 24V input to 13.8V regulated output. Output capacity: Up to 40A continuous current to support medium to current loads. Compatibility: Intended for use with devices and battery systems that require a 13.8V DC supply; suitable for 12Vclass electronics when powered from 24V sources. Performance: Regulated output ensures stable voltage delivery under varying load conditions at rated current. Installation: Designed for integration into 24V electrical systems where a reliable 13.8V source is required. Applications and use cases Vehicle electronics in 24V platforms: Power 13.8V radios, GPS devices, lighting, or incab accessories on trucks, buses, and commercial vehicles that use 24V electrical systems. Battery support and charging: Provide a regulated 13.8V source for charging or maintaining 12V battery banks when connected to a 24V alternator or DC bus (ensure proper batterycharging configuration and monitoring). Industrial and telecom equipment: Run control modules, amplifiers, or communication gear that require 13.8V in industrial control rooms, telecom shelters, or backup power installations fed from 24V distribution. Practical considerations Match wiring, fusing, and connectors to the converter's input and output current to ensure safe operation at up to 40A. Verify device compatibility with a 13.8V DC supply and confirm any batterycharging requirements before connecting. Use appropriate mounting and cooling practices for reliable longterm performance when operating near maximum current. This 24V to 13.8V 40A stepdown DCDC converter offers a practical, direct solution for powering 13.8V devices from 24V systems, helping simplify installations and expand equipment compatibility without changing the primary power architecture.
