DescriptionPRODUCT DESCRIPTION:When you use the product, the module inputs and outputs to be isolated from ground！Input voltage range:4～38VDC(Note:input voltage not exceeding 38V)Output voltage range:1.25-36VDC adjustableOutput current: 0-5AOutput power: 75WHigh efficiency up to 96%Built in thermal shutdown functionBuilt in current limit functionBuilt in output short protection function (limiting current 8A)Input reverse polarity protection: None (if required, high current diode in series with the input).Connect way: Terminal or solder terminals, V-IN is input, V-OUT is outputL x W x H = 61.7 * 26.2 * 15mmApplication:The DC/DC buck module has applications where the input voltage is higher than the output voltage , such as battery, power transformer, DIY adjustable regulated power supply, LCD Monitor and LCD TV portable instrument power supply telecom/networking equipment,24V vehicle notebook power supply, industrial equipment buck. 12V buck to 3.3V, 12V buck to 5V, 24V buck to 5V,24V buck to 12V, 36V buck to 24V etc.This module has adjustable output Voltage and Current.Can also be used as a dedicated charger for Lithium Batteries (Li-Ion, LiPo) as it is capable of CC CVUse as a step-down modules with overcurrent protection capabilities1. Adjust the “voltage potentiometer” so that the output voltage reaches the value you want.2. Use a multimeter to measure the output short-circuit current with 10A stalls, while regulating the “current potentiometer” so that the output current reaches a predetermined overcurrent protection value. (For example, the meter displays the current value of 4A, then you can use the module to a maximum current of 4A)3. Connected to the load.Use as a battery chargerMake sure you need to charge the battery float voltage and charging current; (if lithium parameters 3.7V/2200mAh, then the float voltage is 4.2V, the maximum charging current 1C, ie 2200mA)Under no-load conditions, adjust the “Voltage potentiometer” so that the output voltage reaches the float voltage; (if to 3.7V rechargeable lithium battery, the output voltage can be adjusted to 4.2V)Use a multimeter to measure the output short-circuit current with 10A stalls, while regulating the “current potentiometer” so that the output current reaches a predetermined Charging current value.Charge turn lamp current factory default is 0.1 times the charging current; (Battery during charging current is gradually reduced, if the charge current setting is 1A, then when the charge current is less than 0.1A, blue lights turned off, the green light is on, which means that the battery is fully charged)Connected to the battery charge.(1,2,3,4 steps as: Output is unloaded, do not connect the battery)Use as a LED constant current driver moduleAdjust the “voltage potentiometer” so that the output voltage reaches the value you want.Use a multimeter to measure the output short-circuit current with 10A stalls, while regulating the “current potentiometer” so that the output current reaches a predetermined LED operating current.Connect LED, work.
