The DC to DC Buck Converter 12V 24V to 9V 20A Step Down Voltage Reducer provides a reliable way to derive a 9V supply from common 12V or 24V DC sources. With a maximum current of 20A, it is designed to power 9V devices and circuits from automotive, industrial, and off grid power systems. Key benefits Stable 9V output from 12V or 24V input for devices that require a fixed 9V supply. current capability up to 20A to support modest power loads on 9V circuits. Simple integration for DC power rails in vehicles, machines, and standalone power setups. Enables the use of 9V electronics in environments where only 12V or 24V sources are available. Key attributes Functionality: DC to DC buck converter that steps down voltage from 12V or 24V to 9V. Compatibility: Suitable for 12V and 24V DC systems and devices that operate at 9V. Output: Fixed 9V DC suitable for 9V powered electronics and modules. Current rating: Up to 20A maximum output current.
