5V 3A UBEC Power Supply for RC Receiver with JST Plug Overview A compact UBEC that delivers a stable 5V output at up to 3A through a JST plug. Designed to provide reliable power to RC receivers and small onboard electronics where a regulated 5V supply is required. Key benefits Stable regulated output: Provides a steady 5V supply that helps prevent receiver brownouts and voltage drops during servo or motor load events. Sufficient current for common setups: 3A continuous output supports multiple servos, flight controllers, or other 5V electronics without overloading. Plug and play connection: Standard JST plug enables quick installation with compatible RC receivers and wiring harnesses. Compact and lightweight: Small footprint saves space and reduces weight in tight installations on airplanes, helicopters, multirotors, cars, and boats. Simple to integrate: Works with battery systems and ESCs that require an external 5V regulator to power receivers and peripherals. Features and specifications Output voltage: 5V regulated Maximum output current: 3A Connector: JST plug compatible with common RC receiver inputs Function: UBEC power supply designed to provide regulated 5V power for receivers and onboard electronics Performance: Delivers consistent voltage under varying loads to maintain receiver stability Compatibility Intended for use with RC receivers and 5V onboard electronics that accept a JSTstyle power connector Suitable for electric and model applications where a dedicated 5V supply is preferred or required Typical use scenarios Multirotor flight: Provide a stable 5V supply to the receiver and flight controller while servos and motors draw variable current during maneuvers. Fixedwing model: Power the receiver and multiple servos from a main battery through the UBEC to avoid voltage fluctuations during throttle changes. RC car or boat: Supply reliable 5V power to steering and accessory servos when the onboard ESC does not include a separate 5V regulator. Why choose this UBEC Delivers the core function needed for reliable RC electronics power without added complexity Standard JST connector and compact size make it easy to retrofit into existing models Rated 3A output covers many common receiver and servo configurations for hobby and competition use What to check before installation Confirm your receiver and electronics accept a 5V input via JST connector Verify total current draw of connected devices stays within the 3A continuous rating Route wiring to prevent interference with moving parts and secure the UBEC in a ventilated area if space allows This UBEC offers a practical, straightforward solution for supplying regulated 5V power to RC receivers and associated electronics with a standard JST connection and a 3A capacity.
