Welcome to our store! Features: 1. Highly integrated SMD components for high stability and reliability. 2. Flame retardant plastic casing, safe and reliable. 3. IP67 waterproof and dustproof, easily adapts to various working environments. 4. With over-voltage, over-current, and short-circuit protection. 5. Suitable for car displays, surveillance cameras, fans, water pumps, motors, routers, etc. Specifications: - 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 a load at this time, as the conversion efficiency is low. The output with a 12V load will cause instability and significant output fluctuations. The load should not be too large to start. 2. When the input voltage is AC15-AC28V, the conversion efficiency of the module 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 the DC input is low, with a maximum efficiency 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.
