Sell DC DC Buck Converter CC CV Power Module 1.2-32V 5A Adjustable Regulated power supply Voltmeter ammeter best price

note! ! ! Delivery with accessories, you need to own assembly; module for the DC / DC Buck module, can not enter the transformer directly step down the AC power; to charge the battery, ensure that the module output first power and then connect the battery, the battery is full, first pull Battery, the last module power off, to prevent the battery voltage backflow (preferably at the output of the module is connected to a large current diode can prevent backflow). 1. Product Highlights 1.1. Plexiglass outer shell, beautiful design and generous, key touch texture is good, press the button to set the output voltage, eliminating the need to use a knife; 1.2. The button can control the output to turn off and on, and can set the product power-on default is ON or OFF; 1.3. LCD can display input and output voltage, output current, output power; 1.4. Input reverse polarity protection, reverse connection will not burn; 1.5. 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! 2. Product parameters 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 condition is required, connect the anti-backup diode to the positive side of the output string) Short circuit protection: Yes Size: length * width * height 70.5*48.4*28mm Weight: 62g 3. Function description 3.1. There are two buttons on the left side of the module: IN/OUT, ON/OFF: IN/OUT button to switch the input voltage and output voltage display, long press to switch the output current and output power display; ON/OFF button control output ON or OFF, Long press to set the next time the default output state is ON or OFF. The right side of the module has two buttons: '+' and '-'. Press the '+' button to increase the output voltage by 0.05V. Press and hold it to increase it continuously. Press and hold it again for a continuous slow step increase of 0.1V and 1V. '-' button, the output voltage is reduced by 0.05V,
