Input voltage: 6.5-36V (input voltage is lower than 6.5V, current accuracy is not accurate, LCD display below 5.5V is not normal) Output voltage: 1.2-32V, factory default output 5V. Output current: It can work stably for 3.5A for a long time, and can reach 4.5A with enhanced heat dissipation (adjustable current limit is about 4.2-4.5A) Output power: natural heat dissipation 50W (within 3.5A), enhanced heat dissipation 75W Voltage display: resolution 0.05V, range 1.2-32V, accuracy 0.1V (for customers with precision requirements) Current display: resolution 0.005A, range 0-4.5A, accuracy 0.05A (for customers with precision requirements) Conversion efficiency: about 94% Working current: about 30mA Colour:Blue Material:ABS Package Contents: 1x Buck Module Only the above package content, other products are not included. Note: Light reflection 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.
