9-36V to 12V DC Regulated Buck‑Boost Power Converter Available current options: 5A, 8A, 10A, 12A Key benefits Reliable 12V power from a wide input range: converts any 9-36V source to a steady, regulated 12V output, so your 12V devices keep running whether the input is below or above 12V. Multiple current ratings for the right fit: choose the 5A, 8A, 10A, or 12A version to match your load and avoid oversizing or overheating. Simple integration with 12V systems: ideal for systems that must tolerate variable input voltages (vehicle alternators, batteries, auxiliary power supplies) while delivering a constant 12V output. What it does (function and performance) Auto buck-boost regulation: automatically steps down or steps up the input voltage as required to maintain a constant 12V output. Stable, regulated output: designed to provide consistent 12V power across the full 9-36V input range at the rated current for the selected model. Multiple current capacities: available in 5A, 8A, 10A, and 12A models to suit different power demands without changing the core function. Compatibility and use Works with any 12V load within the chosen current rating (electronics, lights, pumps, control modules). Compatible with common power sources in automotive, marine, off‑grid and industrial environments where input voltage can vary. Practical applications (examples) Automotive and truck systems: power 12V accessories from vehicle electrical systems that may vary between ~9V (cranking) and higher voltages on heavy vehicles or charging systems. RVs, boats, and solar setups: maintain steady 12V supply for lights, pumps, and control electronics when input comes from batteries, alternators, or solar charge controllers. Industrial equipment and control panels: provide a regulated 12V rail from a wide-range DC bus for sensors, relays, or communication modules. Installation and selection tips Select the model rated for the continuous current your load requires (5A, 8A, 10A, or 12A). Mount and wire according to standard practice for DC power modules; ensure adequate cooling and correct polarity to achieve stable 12V regulation. This power module provides a straightforward, reliable way to get a constant 12V output from 9-36V inputs with selectable current ratings, using automatic buck-boost regulation to handle both lower and higher input voltages.
