Features High Performance: Uses synchronous rectification technology for high conversion efficiency and stable performance; input voltage should be at least 3V higher than output voltage. Voltage Transformation: Converts an unstable 24V DC power supply into a stable 12V DC output with high efficiency, low heat generation, and effective heat dissipation. Durable Design: Fully sealed construction with an outer enclosure that acts as a heat sink; designed to be waterproof, shock-resistant, humidity-resistant, and dustproof for extended service life. Safety Protections: Includes reverse polarity protection, over-current protection, over-temperature protection, and over-voltage protection for safe operation. Wide Compatibility: Suitable for various electronic applications such as radio systems, car audio, LED displays, motors, mobile devices, and hobby projects. Specification Item Type: 24V to 12V Buck Converter Material: ABS Application: Universal fit for trucks Package List: 1 x Voltage Regulator
