Functions: Highly integrated SMD components for high stability and reliability. Fireproof plastic housing, safe and reliable. IP67 waterproof and dustproof, easily adapts to different working conditions. With overvoltage, overcurrent and short circuit protection. Suitable for car screen, surveillance camera, fan, water pump, motor, router, etc. Specification: Input Voltage: AC 10-28V Output voltage: DC12V ±0.25V Output current: 1A/2A/3A/5A (optional) Output power: 12W/24W/36W/60W Continuous operating current: 2A/3.5A Conversion efficiency: 96% Degree of protection: IP67 Operating temperature: -20°C to 80°C Package includes: 1 x Converter When the input voltage is AC10-14V, the output current is less than 1A; when the output voltage is 12V, it is not recommended to use with load at this time, because the conversion efficiency is low, which may cause output instability and large power fluctuations. Heavy load may fail to start. When the input voltage is AC15-AC28V, the module conversion efficiency is up to 90%, and the output voltage can maintain DC12V ±0.25V. The 3A module supports continuous operation within 2A, and the 5A module supports continuous operation within 3.5A. Input voltage also supports DC input, with a range of DC16-36V. DC input efficiency ranges from 83% to 90%. When using DC input, the input terminal is not polarity sensitive. Note: Due to differences in lighting and screen settings, the item's color may vary slightly from the images. Slight dimensional differences may occur due to manual measurement.
