1 Piece Of 5a High Power Xl4015 75w Dc-dc Adjustable Step-down Module

When the on-board voltmeter displays the output voltage, press and hold the button on the right for 2 seconds and then release it. The voltmeter and the output voltage indicator OUT will flash simultaneously, and the output voltage adjustment mode will be entered;for the same reason, display on the voltmeter When inputting voltage, press and hold the button on the right for 2 seconds and then release, the voltmeter and the input voltage indicator IN will flash simultaneously, and the input voltage adjustment mode will be entered at this time;Tap the right button to increase the voltage by one unit, and tap the left button to decrease the voltage by one unit; since the voltage value of a unit is less than 0.1V, you need to press 1-5 times to see the voltmeter Changed by 0.1V. The specific number of consecutive keystrokes depends on the currently displayed voltage value. The higher the currently displayed voltage, the fewer the number of times to press;After the voltage adjustment is completed, press and hold the right button for 2 seconds and then release it. At this time, you can exit the voltage calibration mode, and all parameter settings will be automatically saved after power-off.Application range:This module can be used in the step-down field where the input voltage is higher than the output voltage, such as batteries, power transformers, DIY adjustable regulated power supplies, 24V car pen-based power supplies, industrial equipment step-downs, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V, etc.Module performance and characteristics:With power indicatorWith voltmeter display and the voltmeter can be self-calibrated. It adopts a more advanced voltage microprocessor, the error of the voltmeter is 0.05V, and the range is 0~40V. (Note: to ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4.5V)Touch the button to switch between measuring input or output voltage, and there is an indicator light to show which voltage is being measured, and the setting is saved, even if the power is turned off and on again.Size 60 x 37 x 18mmWeight 28gColour:blueMaterial:Metal + plasticPackage Contents:1 * 5A high power XL4015 75W DC-DC adjustable step-down module 4 * nut 4 * screw 1 * radiatorNote: In this adjustment method, you only need to calibrate once to obtain the voltage value on the entire voltage range. This function is designed to meet your higher accuracy requirements, please rest assured to use it.Only the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
