XL4015 DC-DC Adjustable Step-down Module 75W 5A High Power Far Exceeds 2596 With Voltmeter DisplayItem NO.: XL4015E

XL4015 DC-DC Adjustable Step-down Module With Voltmeter Display

Module Highlights:

5A high-power, high-efficiency, reduced voltage, and low ripple! With power indicator light! On board voltmeter, voltmeter can self calibrate, and there will never be the problem of inaccurate voltmeter!! With heat dissipation fins! Free copper pillars!

Module Performance And Characteristics:

● With power indicator light

● With voltmeter display and voltmeter self calibration. More advanced voltage microprocessors are used, the error of 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)

● Gently touch the button to switch between measuring input or output voltage, and there is an indicator light indicating which voltage is being measured, and the settings are saved, even if the power is turned off and turned on again.

● The voltmeter can be closed, which can be easily realized by tapping the left button when not needed.

● Equipped with wiring terminals, it can be easily used without soldering iron, and the solder wire connection points are retained.

● Input voltage 4.0-38V. (The input voltage must be more than 1.5v higher than the output voltage)

● Adjustable output voltage range: 1.25V~35V, continuously adjustable. (The input voltage must be 1.5V higher than the output voltage)

● The output current can reach 5A, and it is recommended to use it within 4.5A.

● The output power can reach 75W.

● High conversion efficiency, up to 96% (efficiency is related to input and output voltage, current, and voltage difference)

● Load adjustment rate S (I) ≤ 0.8%, voltage adjustment rate S (u) ≤ 0.8%

● Equipped with overheating protection and short circuit protection functions

● Size 60 * 37 * 18mm

● Weight 28g

Self Calibration Method Of On-board Voltmeter:

1. When the on-board voltmeter displays the output voltage, long press the right button for 2 seconds and then release it. The voltmeter and the output voltage indicator "OUT" flash synchronously, and then enter the output voltage adjustment mode; Similarly, when the voltmeter displays the input voltage, long press the right button for 2 seconds and then release it, the voltmeter and the input voltage indicator "IN" flash synchronously, and 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 value of a unit is less than 0.1V, you need to press it 1-5 times continuously to see that the voltmeter has changed 0.1V. The specific number of times you press it continuously depends on the current displayed voltage value. The higher the current displayed voltage, the fewer times you press it;

3. After the voltage adjustment is completed, press and hold the right button for 2 seconds before releasing it. At this point, the voltage calibration mode can be exited, and all parameter settings will be automatically saved after power off.

Note: With this adjustment method, you only need to calibrate once to obtain accurate voltage values across the entire voltage range. This function is designed to meet your higher accuracy requirements. Please rest assured to use it.

Application Scope:

This module can be applied in the field of voltage reduction where the input voltage is higher than the output voltage, such as batteries, power transformers, DIY adjustable regulated power supplies, 24V vehicle mounted laptop power supplies, industrial equipment voltage reduction, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V, etc.
