5A 4V-38V XL4015 DC-DC Adjustable Step Down Module with Voltmeter

5A 4V-38V XL4015 DC-DC Adjustable Step Down Module

Module performance and characteristics:

● With power indicator
● With voltmeter display and the voltmeter can be self-calibrated. Using a more advanced voltage microprocessor, the voltmeter error 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.
● The voltmeter can be turned off, and it can be easily realized by touching the button on the left when it is not needed.
● With terminal blocks, it is convenient to use without soldering iron, and the connection points of welding wires are reserved.
● input voltage of 4.0 ~. 3 . 8 V . (The input voltage must be more than 1.5v higher than the output voltage )
● adjustable output voltage range of 1.25V ~ . 3 . 5 V is 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, output voltage, current, and pressure difference)
● Load regulation rate S ( I ) ≤ 0.8% , voltage regulation rate S ( u ) ≤ 0.8%
● With overheating protection and short circuit protection function
● Size 6 0 *3 7 *18mm

Voltmeter calibration method:

1. Onboard voltmeter shows that the output voltage, long press the right button 2 seconds to loosen, voltmeter, and the output voltage indicator light [OUT] synchronous flash, at this time into the output voltage regulation mode; Similarly, when the input voltage IN the voltmeter display, long press the right button 2 seconds to loosen, voltmeter, and the input voltage indicator light [IN] synchronous flash, at this time into the input voltage adjustment mode.

2. Light touch button on the right side, the voltage value is adding up a unit; Press the left button, minus a unit; Due to a unit of voltage is less than 0.1 V, so you need to press the 1-5 consecutive can see the voltmeter change 0.1 V, the concrete continuous button several times depends on the current display voltage, current shows that the higher the voltage, the fewer the number of press.

3. After the voltage adjustment, long press the right button for 2 seconds, release, to exit the output voltage calibration mode, all the parameters set to automatically power down saving.

The DC/DC buck module applications the input voltage is higher than the output voltage of the buck field, 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.

Note:

The input voltage should be more 1.5V than output!
