LM2596S DC-DC 4-40V to 1.25-37V Adjustable buck module Voltage Regulator LED:
1. With voltmeter display and voltmeter can be self-calibrated. The advanced voltage microprocessor is used, the voltmeter error is ±0.05V, and the range is 0~40V. (To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4.5V)
2. 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.
3. The voltmeter can be turned off, and it can be easily achieved by tapping the left button when it is not needed.
4. With terminal block, no soldering iron can be used easily, and the wire bonding point is retained.Description:
1. Input voltage 4.0~40V. (The input voltage must be 1.5v higher than the output voltage)
2. Adjustable output voltage range from 1.25V to 37V continuously adjustable. (The input voltage must be 1.5V higher than the output voltage)
3. Output current 3A, it is recommended to use within 2.0A, high current needs to strengthen heat dissipation.
4. Output power 20W, more than 15W, please strengthen the heat.
5. High conversion efficiency, with an average of 88% (efficiency related to input, output voltage, current, voltage difference)
6. With reverse connection protection, reverse connection does not burn
7. Size 6.1*3.4*12cm (length * width * height)
8. Weight: 22g
Application range: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, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V, etc.
Voltmeter self-calibration method:
1. When the on-board voltmeter displays the output voltage, press and hold 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;
2. 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;
3. After the voltage adjustment is completed, long press the right button for 2 seconds and then release, then the voltage calibration mode can be exited, and all parameter settings are automatically powered off.
Note: This adjustment method allows you to obtain accurate voltage values over the entire voltage range with only one calibration. This function is designed to meet your higher accuracy requirements. Please feel free to use it.
