XL4005 XL4015 5A high-power 75W DC-DC adjustable step-down power supply module voltage display digital display
This module is different from the LM2596 voltage reduction module on the market. The design power of the chips used in them is 15W and 50W respectively. This voltage reduction module in our store uses original and genuine upgraded chips, which are superior to similar products in terms of input and output voltage range, output power and efficiency. The power can reach 75W, with a very high cost performance ratio.
Module highlights:
5A high power, high efficiency, low ripple!
With power indicator!
On board voltmeter, the voltmeter can be self calibrated. yong is far from having the problem of inaccurate voltmeter!!
With heat sink!
Give away bronze pillars!!!
Module performance and characteristics:
With power indicator
With voltmeter display and self calibration. More advanced voltage microprocessor is adopted, with voltmeter error of ± 0.05V and range of 0~40V. (Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4.5V)
Touch the key to switch the input or output voltage measurement, and an indicator lamp will display which voltage is being measured, and save the settings, even if the power is cut off and the machine is started again.
The voltmeter can be closed, and it can be easily realized by touching the left button when it is not needed.
With terminal blocks, it can be used easily without soldering iron, and welding wire connection points are reserved.
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~36V, 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 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 differential voltage)
Load regulation ratio S (I) ≤ 0.8%, voltage regulation ratio S (u) ≤ 0.8%
With overheating protection and short circuit protection functions
Size 66 * 39 * 18mm
Weight 28g
Self calibration method of on-board voltmeter:
1. When the on-board voltmeter displays the output voltage, press and hold the right button for 2 seconds and 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, and tap the left button to decrease the voltage by one unit; As 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 changes 0.1V. The specific number of times you press it depends on the current displayed voltage value. The higher the current displayed voltage is, the fewer times you press it;
3. After the voltage adjustment is completed, long press the right key for 2 seconds and then release it. At this time, you can exit the voltage calibration mode, and all parameter settings will be automatically power off and saved.
Note: With this adjustment method, you can get accurate voltage values on the whole voltage range only after calibration once. This function is designed to meet your higher accuracy requirements. Please feel free to use it.
Scope of application:
This module can be used in the field of voltage reduction where the input voltage is higher than the output voltage, such as storage battery, power transformer, DIY adjustable regulated power supply, 24V vehicle mounted pen and notebook power supply, industrial equipment voltage reduction, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V, etc.
Please note:
Some customers said that the output voltage of the module could not be adjusted and was always equal to the input voltage. When you encounter this problem, please rotate the potentiometer counterclockwise for more than 10 turns, and then use the module to adjust the voltage normally. Because the default output voltage of the step-down module is about 20V when it leaves the factory.
