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: DC 12V ±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 AC 10-14V, the output current is less than 1A; when the output voltage is 12V, it is not recommended to operate under load, as the conversion efficiency is low, which may cause output instability and large power fluctuations. Heavy loads may fail to start. When the input voltage is AC 15-28V, the module conversion efficiency is 90%, and the output voltage can maintain DC 12V ±0.25V. The 3A module supports continuous operation up to 2A, and the 5A module supports continuous operation up to 3.5A. Input voltage also supports DC input with a range of DC 16-36V. DC input conversion efficiency ranges from 83% to 90%. When using DC input, the input terminals are not polarized. Note: Due to differences in lighting and monitor settings, the item's color may vary slightly from images. Slight dimensional differences may occur due to manual measurement.
