This module is different from the LM 2596 and XL4005 step-down modules on the market. The chip design power is 15W and 50W respectively. This buck module uses the original authentic upgrade chip, which is in the input and output voltage range, output power and efficiency. To be superior to similar products, the power can reach 75W, which has a high-cost performance.
Module Performance and Features:
With power indicator
With voltmeter display and voltmeter self-calibration.A more advanced voltage microprocessor is used, 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 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.
The voltmeter can be turned off, and it can be easily achieved by tapping the left button when it is not needed.
With terminal block, no soldering iron can be used conveniently, and the wire bonding point is retained.
Input voltage4.0~38V. (The input voltage must be 1.5v higher than the output voltage )
Adjustable output voltage range from1.25V to 36V continuously adjustable. (The input voltage must be 1.5V higher than the output voltage )
Output current up to5A, it is recommended to use within 4.5A.
Output power up to75W.
High conversion efficiency, up to96% (efficiency related to input, output voltage, current, voltage difference)
Load regulation rateS ( I ) ≤ 0.8% , voltage regulation rate S ( u ) ≤ 0.8%
With overheat protection and short circuit protection
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, 24V car pen power supply, industrial equipment step-down, 12Vto 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V, etc.
Onboard Voltmeter Self-Calibration Method:
When the onboard voltmeter displays the output voltage, press and holds the right button for 2 seconds to release, the voltmeter and the output voltage indicator “OUT” flash synchronously. At this time, the output voltage adjustment mode is entered; similarly, the voltmeter is displayed. 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;
Tap the right button to increase the voltage by one unit. Tap the left button to lower the voltage by one unit. Since the voltage of one unit is less than 0.1V, you need to press 1-5 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;
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.
