AC DC Power Supply Module AC 1028V to DC 12V Buck Converter AC DC Step Down Power Supply Module Step Down Power Supply AC 1028V to DC 12V Buck Converter AC DC Step Down Power Supply Module Specification: 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 environment. 4.With overvoltage, overcurrent, short circuit protection. 5.Suitable for car screen, monitor camera, fan, water pump, motor, router, etc. Specification: Input voltage: AC 10-28V Output voltage: DC12V0.25V 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; when the output voltage is 12V, it is not recommended to output with load at this time, because the conversion efficiency is low at this time; the output 12V after loading will cause the output to be unstable and big output fluctuation.The load is too big to start! 2. When the input voltage is AC15-AC28V, the conversion efficiency of the module is 90%, and the output voltage can maintain DC12V0.25V. 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. DC input conversion efficiency is low, the conversion efficiency is 83%-90% maximum; when DC input, the input terminal is not divided into positive and negative poles!
