Welcome to our shop! Features: 1. Highly integrated SMD components for high stability and reliability. 2. Flame retardant plastic housing, safe and reliable. 3. IP67 waterproof and dustproof, easily adapt to various working environments. 4. With overvoltage, overcurrent, short circuit protection. 5. Suitable for car screens, monitor cameras, fans, water pumps, motors, routers, 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 working current: 2A/3.5A - Conversion efficiency: ≥96% - Protection level: IP67 - Working temperature: -20~80℃ Package list: - 1 x Converter Note: 1. When the input voltage is AC10-14V, the output current is less than 1A. It is not recommended to output with load at this time due to low conversion efficiency. The output 12V after loading will cause output instability and large fluctuations. The load should not be too big to start. 2. When the input voltage is AC15-AC28V, the module's conversion efficiency is ≥90%, and the output voltage can maintain DC12V±0.25V. At this time, the 3A module can support long-term work within 2A, and the 5A module can support long-term work within 3.5A. 3. The input voltage also supports DC input, and the DC input range is DC16-36V. The conversion efficiency of DC input is low, with a maximum of 83%-90%. When using DC input, the input terminals are not divided into positive and negative poles. 100% Satisfaction: Our customers are our top priority.
