XL4015 Module High Conversion Efficiency Adjustable DCDC Buck with Voltage Meter Display 75W

About this item

• Feature: 1. This module can be applied to the buck field where the input voltage is higher than the output voltage, such as battery, power transformer, DIY adjustable power supply, industrial equipment step?down. 2. With power indicator, 5A high power high efficiency step?down low ripple 3. With heat sink and standoff for overheat protection and short circuit protection 4. With voltmeter display and the voltmeter can be selfcalibrating 5. Using a more advanced voltage microprocessor, voltmeter error + 0.05V, range 0 ~ 40V 6. Touch the button to switch the measurement input or output voltage, and the indicator light shows which voltage is being measured, and save the settings, even if it is powered off and then on. 7. The voltmeter can be turned off and easily tapped left side when you don not need it. 8. With terminal, no soldering iron is also convenient to use, and retain the wire bond point Specification: Item Type: XL4015 ModuleInput Voltage: 4.0~38V (the input voltage must be 1.5V higher than the output voltage) Adjustable Output Voltage Range: 1.25V ~ 35V, Continuously Adjustable (input voltage must be 1.5V higher than the output voltage) Output Current: Up to 5A, recommended for use within 4.5A Output Power: Up to 75W High Conversion Efficiency: Up to 96percent (efficiency related to input, output voltage, current, voltage difference) Load Regulation Rate: S(I) less than 0.8percent Voltage Regulation: S(u) less than 0.8percent Onboard Voltmeter SelfCalibration Method: 1. When the onboard voltmeter shows the output voltage, press and hold the right button for 2 seconds and then release it. The voltmeter and output voltage indicator OUT flash synchronously. At this time, the output voltage adjustment mode is entered. Similarly, the voltmeter displays. When inputting the voltage, long press the right button for 2 seconds and then release, the voltmeter and the input voltage indicator IN flash synchronously, then enter the input voltage adjustment mode 2. Tap the right button to increase the voltage by one unit. Tap the left button to decrease the voltage by one unit. Since the voltage of one unit is less than 0.1V, you need to press 15 times to see the voltmeter. Changed by 0.1V, the specific continuous button press depends on the currently displayed voltage value, the higher the current display voltage, the fewer the number of presses 3. After the voltage adjustment is completed, press and hold the right button for 2 seconds and then release. At this point, the voltage calibration mode can be exited, and all parameter settings are automatically powered down. Note: This adjustment method only needs to be calibrated once to get accurate voltage value over the entire voltage range. This function is designed to meet your higher accuracy requirements. Please feel free to use it.

Package List: 1 x Module4 x Standoff4 x Nuts1 x Heat sink Note: The module output voltage cannot be adjusted and is always equal to the input voltage. When you have this problem, please turn the potentiometer counterclockwise for more than 10 turns, then use the module to adjust the voltage normally. Because the default output voltage of set down module is about 20V.This module can be applied to the buck field where the input voltage is higher than the output voltage, such as battery, power transformer, DIY adjustable power supply, industrial equipment step?down.
