Description When you use the product. The module inputs and outputs to be isolated from ground! Specifications 1、Input voltage range:6~38VDC(Note:input ... morevoltage not exceeding 38V) 2、Output voltage range:1.25-36VDC adjustable 3、Output current: 0-5A 4、Output power: 75W 5、High efficiency up to 96% 6、Built in thermal shutdown function 7、Built in current limit function 8、Built in output short protection function 9、Input reverse polarity protection: None(if required. High current diode in series with the input) 10、L x W x H =61.7*26.2*15mm 11、Weight: 20g Application 1、Use as a step-down modules with overcurrent protection capabilities Usage: 1) 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. 2、Use as a battery charger Usage: 1) Make 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) 2) 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) 3) 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. 4) 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) 5)co

Features This product is a 180 KHz fixed frequency PWM buck(step-down) DC/DC module.Capable of driving a 5A load with high efficiency, low ripple and ... moreexcellent line and load regulation.The module with a voltage meter to display the input voltage and output voltage, and the voltage can be corrected through the button to improve the accuracy of the voltmeter. Features: 1. LED power indicator. 2. Button to switch measurement of the input or output voltage. And LED indicates the current measurement of the input or output voltage; The nixie tube can be turned off by another button. Mentioned states are able to be memorized, is not lost even if the power is disconnected. On-board marked"IN" LED is turned on, the nixie tube display input voltage value, OUT" LED bright display is the output voltage value) 3. Special launch. The voltmeter calibration function, will never exist voltmeter inaccurate! Voltmeter calibration method: 1) Output voltage calibration steps Step 1. Adjust the right button so that"OUT" LED lighted, the voltmeter shows the value of output voltage; Press the right button for more than 2 seconds, release, voltmeter and"OUT" LED flashes in synchronization so that you enter the output voltage calibration mode. Step 2. Press the right button(normal speed) the voltage value is adding up a unit; Press the left button, minus a unit; Due to a unit is less than 0.1V, the minimum voltage display to 0.1V, so you need to continuously press 1-5 times to see the voltmeter change 0.1V, how many times voltmeter change 0.1V by pressing the key, depending on the current display voltage, the higher the voltage, the fewer the number of press. Step 3. Press the right button for more than 2 seconds, release, to exit the output voltage calibration mode. All parameters set to automatically power down to save. 2) Input voltage calibration steps Step 1. Adjust the right button so that"IN" LED lighted, the voltmeter shows the value of input voltage; press the right button for more tha
