Features High Performance: Uses synchronous rectification technology for high conversion efficiency and stable performance; input must be at least 3V higher than output. Voltage Transformation: Converts unstable 24V DC input to stable 12V DC output with high efficiency, low heat generation, and effective heat dissipation. Long Service Life: Fully sealed design with outer enclosure acting as a heat sink; designed to be waterproof, shock-resistant, humidity-resistant, and dustproof for increased durability. Safe Operation: Includes reverse connection protection, over-current protection, over-temperature protection, and over-voltage protection for enhanced safety. Wide Application: Suitable for electronic hobby projects, radio equipment, car audio systems, LED displays, motors, mobile devices, and other DC-powered electronics. Specification Item Type: 24V to 12V Buck Converter Material: ABS Application: Universal fit for trucks Package List: 1 x Voltage Regulator
