Highly integrated SMD components for high stability and reliability. Flame retardant plastic housing ensures safe and reliable operation. IP67 rated for waterproof and dustproof performance, suitable for various working environments. Built-in protection against overvoltage, overcurrent, and short circuit conditions. Compatible with car screens, monitoring cameras, fans, water pumps, motors, routers, and other DC12V devices. Specifications: Input voltage: AC 10-28V Output voltage: DC 12V ±0.25V Output current: 1A / 2A / 3A / 5A (selectable) Output power: 12W / 24W / 36W / 60W Continuous working current: 2A / 3.5A Conversion efficiency: Up to 96% Protection rating: IP67 Operating temperature: -20°C to +80°C Note: - When input voltage is AC 10-14V, output current is less than 1A. Under load, output may become unstable with significant fluctuation due to low conversion efficiency. Not recommended for heavy loads in this range. - When input voltage is AC 15-28V, conversion efficiency is approximately 90%, and output voltage remains stable at DC 12V ±0.25V. The 3A model supports continuous operation up to 2A; the 5A model supports continuous operation up to 3.5A. - DC input is supported within the range of DC 16-36V. Conversion efficiency under DC input ranges from 83% to 90%. Polarity on the input terminal is not required for DC input. Package includes: 1 x Converter
