Y1 12V to 13.8V 3A Voltage Regulator Boost Power Converter (NonIsolated) Convert a 12V DC source to a stable 13.8V DC output with the Y1 boost regulator. Designed to deliver up to 3A, this nonisolated converter provides a straightforward way to power or charge devices that require 13.8V from a standard 12V system. Key benefits Provides a regulated 13.8V output from a 12V source so devices that expect higher voltage run reliably. Delivers up to 3A continuous output to support many small to medium loads without overloading the source. Nonisolated design simplifies integration into systems where input and output share a common ground. Helps maintain performance of 13.8V equipment and supports proper charging of leadacid and sealed batteries that need a higher charging voltage. Main attributes Model: Y1 Function: Boost (stepup) voltage regulator / power converter Input → Output: 12V to 13.8V Maximum output current: 3A Topology: Nonisolated (common ground) Use environment: Intended for DC 12V systems Compatibility and typical applications Works with 12V vehicle batteries, 12V power supplies, and similar DC sources. Suited for devices and accessories specified for 13.8V operation. Can be used where a modest boost in voltage is needed without isolation. Recommended use cases Amateur radio and CB transceivers: Provide a stable 13.8V supply from a vehicle or 12V battery for consistent radio performance and proper charging of internal batteries. Automotive and marine 13.8V accessories: Power 13.8V modules, chargers, or sensors from a common 12V electrical system. Backup power or laboratory setups: Step a 12V bench supply up to 13.8V when testing or operating equipment that requires that exact nominal voltage. Installation and safety notes Because this converter is nonisolated, input and output grounds are common — verify compatibility with your system grounding scheme before installation. Place the unit where airflow allows heat dissipation appropriate to the load and environment. Follow standard wiring practices: use appropriate wire gauge and secure connections. Consider an inline fuse on the input for added protection. What it solves Eliminates the need for a separate 13.8V battery or supply when only a 12V source is available. Ensures devices designed for 13.8V receive the correct voltage for reliable operation and correct charging behavior. Simplifies retrofitting or upgrading equipment in vehicles, boats, and other 12V systems. The Y1 12V→13.8V 3A boost converter offers a direct, practical solution for stepping up 12V DC to a regulated 13.8V output where a nonisolated design and up to 3A of current are sufficient.
