1. Plexiglass shell, beautiful and generous design, the buttons feel good texture, the buttons adjust the output voltage, save the use of knives 2. The button can turn off and on the output, the product is powered on and the default is ON or OFF 3. LCD can display and output voltage, output current, and output power 4. Input reverse connection protection, reverse connection will not burn out 5. High efficiency above 93%, high current, low heat output, arbitrary adjustment of output voltage 1.2-32V, constant current value adjustment about 0-4.5A, suitable for office power supply, high power LED constant current drive, lithium battery charging, etc.! Input voltage: 6.5-36V (input voltage is less than 6.5V, current is not accurate, less than 5.5V, liquid crystal display is abnormal) Output voltage: the factory default output is 5V. Output current: It can work stably at 3.5A for a long time, and it can reach about 4.5A under enhanced heat dissipation (adjustable limit current is about 4.2-4.5A) Output power: natural heat dissipation 50W (less than 3.5A), enhanced heat dissipation 75W Voltage display: resolution of 0.05V, range of 1.2-32V, accuracy of about +/- 0.1V (accuracy requires caution!) Current display: resolution 0.005A, range 0-4.5A, accuracy +/- 0.05A (people with accuracy requirements!) Conversion efficiency: about 94% Working current: about 30mA Reverse input protection: Yes Anti-backflow at the output: None (If the battery has power, on the module and then turn off the battery to that the battery voltage is lower than the output voltage; if possible, connect the positive electrode of the anti-backflow output string) Short circuit protection: Yes colour: blue Material: plastic Size: 70.5x48.4mm Package Contents: 1 x p down module Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
