Highly integrated SMD components for high stability and reliability. Flame retardant plastic housing provides safe and reliable performance. IP67 rated for waterproof and dustproof protection, suitable for various working environments. Built-in overvoltage, overcurrent, and short circuit protection. Compatible with car screens, monitor 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 (optional) 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 Package includes: 1 x DC-DC Converter Note: - When input voltage is AC 10-14V, output current is less than 1A. Output voltage may become unstable under load due to reduced conversion efficiency, not recommended for heavy loads at this range. - When input voltage is AC 15-28V, conversion efficiency reaches up to 90%, output voltage remains stable at DC 12V ±0.25V. The 3A module supports continuous operation up to 2A; the 5A module supports continuous operation up to 3.5A. - Supports DC input within the range of DC 16-36V. Conversion efficiency under DC input ranges from 83% to 90%. Input terminals are polarity-insensitive for DC input.
