1036V to 13.8V DC to DC BuckBoost Power Supply Converter Regulator 25A Key benefits Provides a stable 13.8V output from a wide 10–36V DC input range. Ideal where supply voltage fluctuates above or below the target. Buckboost topology both steps down and steps up automatically, eliminating the need for separate converters when input voltage varies. 25A continuous output capability supplies highercurrent 12V loads and charging circuits without frequent thermal limits. Simplifies system design by delivering a fixed, regulated 13.8V output for 12V systems and accessories that require a consistent voltage. What this product solves Prevents undervoltage or overvoltage conditions for electronics when vehicle, marine, or battery voltages are outside the normal 12V window. Enables reliable charging and operation of 12V batteries and equipment from alternators, batteries, or power sources between 10V and 36V. Replaces multiple components by providing a single, compact regulator that both boosts and bucks as needed. Core functionality and specifications Input voltage range: 10V to 36V DC. Output voltage: regulated 13.8V DC (nominal). Output current: up to 25A continuous. Converter type: DCtoDC buckboost regulator (automatic stepup and stepdown). Compatibility and typical use Compatible with 12V electrical systems and devices that require a steady 13.8V supply. Can be used with alternators, batteries, solar battery banks, or other DC sources within the 10–36V input window. Suitable for automotive, marine, RV, offgrid, and industrial 12V applications. Performance and reliability (practical considerations) Designed to maintain a constant 13.8V output across the stated input range and under loads up to 25A. Useful where supply voltage can drop (battery discharge, starter cranking) or rise (highervoltage alternators or systems), since the buckboost design adapts automatically. When integrating, ensure adequate cooling and wiring sized for 25A continuous current to maintain expected performance. Use cases and applications Vehicle charging and accessory power: Keep radios, fridges, and other 12V accessories running at a stable charging voltage even when vehicle battery voltage fluctuates while starting or charging. Marine and RV systems: Provide consistent 13.8V for battery charging and 12V electronics when shore power, alternator, or battery voltages vary. Solar and offgrid setups: Regulate output for 12V battery charging or 12V equipment when input from solar charge controllers or battery banks falls anywhere between 10V and 36V. Installation and integration tips Mount in a location with good airflow and away from direct heat sources; observe polarity when connecting input and output. Use appropriately rated cables and fuses sized for 25A continuous current and the installation environment. Confirm the regulated 13.8V output with a meter during initial setup and under expected load conditions. Why choose this converter Straightforward solution for systems that need a reliable 13.8V supply from widely varying DC sources. Eliminates the need to choose between a stepup or stepdown regulator by providing both functions in one unit. 25A rating supports highercurrent 12V devices and charging tasks without multiple converters. Specifications summary Input: 10–36V DC Output: 13.8V DC (regulated) Maximum output current: 25A Converter type: Buckboost DCDC regulator If your system requires a steady 13.8V supply from variable DC inputs and demands up to 25A, this 1036V to 13.8V DC to DC BuckBoost Power Supply Converter Regulator 25A provides a single, reliable solution.
