ITEM NAME:5A DC-DC Boost Step-Up/Down Constant Voltage Current Power Supply Module ZYBX Description: Input reverse polarity protection,reverse connection will not burn; LCD can display input and output voltage,output current, output power; High efficiency over 93%,large current,small heat,output voltage 1.2-32V arbitrary regulation,constant current value of about 0-4.5A adjustment, suitable for office power,high-power LED constant current drive,lithium battery charging and so on Specifications: Input voltage:6.5-36V (input voltage less than 6.5V,current is not accurate, less than 5.5V,LCD display is not normal) Output voltage:1.2-32V, factory default output 5V. Output current:Can work stably at 3.5A for a long time, and 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 0.05V,range 1.2-32V, accuracy of about  ± 0.1V (accuracy demanding carefully shot!) Current display: resolution 0.005A,range 0-4.5A,accuracy  ±0.05A (precision for those who require strict accuracy!) Conversion efficiency:about 94% Working current: about 30mA Reverse input protection:Yes Anti-backflow at the output end:None (If the battery is charged, first power on the module and then connect the battery, and ensure that the battery voltage is lower than the output voltage; if the.Output power: natural heat dissipation 50W (less than 3.5A),enhanced heat dissipation 75W. The CHAR indicator is the charging indicator. When charging,it is on.The FULL indicator is full.If the set constant current value is 2A,the charging When the current reaches 0.2A or less,turn on the lamp, the FULL lamp is on,and the CHAR lamp is off.
