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: 96% Protection level: IP67 Working temperature: -20°C to 80°C Package list: 1 x Converter Note: 1. When the input voltage is AC 10-14V, the output current is less than 1A. At an output voltage of 12V, it is not recommended to operate under load, as conversion efficiency is low. Loading may cause unstable output and significant fluctuations. Excessive load may prevent startup. 2. When the input voltage is AC 15-28V, the module’s conversion efficiency is 90%, and the output voltage remains stable at DC 12V ± 0.25V. The 3A module supports continuous operation up to 2A, and the 5A module supports continuous operation up to 3.5A. 3. DC input is supported within the range of DC 16-36V. DC input results in lower conversion efficiency, with a maximum range of 83% to 90%. For DC input, the input terminals are not polarity-sensitive.
