LM2596 DC-DC adjustable antihypertensive module with voltage meter display LM2596S voltage voltage power supply module

Reminder: Most of the modules in this store only provide description or delivery information. There are no technical consulting support. Please be careful to shoot.

Module highlights:

1. A comfortable price, intelligent and humane design, have super high cost performance!

2. The voltage meter, the voltage table can be calibrated by itself, and there will never be a problem with the problem of accurate voltage gauge!

Module performance and characteristics:

● The voltage meter is displayed and the voltage can be calibrated by itself.A more advanced voltage microprocessor is used, the voltage meter error is ± 0.05V, and the range is 0 ~ 40V.(To ensure the accuracy of the voltage meter, please ensure that the input voltage is above 4.5V)

● Touch the button to switch the measuring input or output voltage, and there are indicator lights show which voltage is being measured, and the settings are saved, even if the power is turned off and then turned on.

● The voltage table can be closed. When it is not needed, it can be easily implemented by touching the left button.

● With the wiring terminal, it can be easily used without a soldering iron, and the welding line wiring point is retained.

● Input voltage 4.0 ~ 40V.(The input voltage must be more than 1.5V higher than the output voltage)

● The adjustable output voltage range is 1.25V ～ 37V continuously adjustable.(Input voltage must be 1.5V higher than the output voltage)

● Output current 3A, it is recommended to use it in 2.0A, and large current needs to strengthen heat dissipation.

● The output power is 20w, please strengthen the heat dissipation over 15W.

● High conversion efficiency, an average of 88%(efficiency is related to input, output voltage, current, voltage difference))

● Reverse connection protection, do not burn the reverse connection

● Have the function of overheating and short circuit protection

● Size 6.1*3.4*12cm (length*width*height)

● Weight: 22g

Scope of application:

This module can be applied to the antihypertensive field with the input voltage higher than the output voltage, such as batteries, power transformers, DIY adjustable voltage voltage power supply, 24V vehicle strokes calculated power supply, industrial equipment reduction, 12V to 3.3V, 12V to 5V, 12V to 5V, 12V to 5V, 12V to 5V, 12V to 5V.24V to 5V, 24V to 12V, 36V to 24V, etc.

Self -calibration method of plate voltage meter:

1. When the output voltage is displayed, the right side of the right side is loosen after 2 seconds.When the input voltage is input, the right side of the right side is loosened after 2 seconds, and the voltage meter and input voltage indicator light "in" flickered synchronously. At this time, enter the input voltage adjustment mode;

2. Touch the right button on the right, increase the voltage one unit, touch the left button gently, and reduce the voltage by one unit; because the voltage value of a unit is less than 0.1V, you need to press it 1-5 times in a row to see the voltage gauge to see the voltage gauge continuously to see the voltage gauge.The change has been 0.1V, and the specific continuous keys depend on the voltage value of the currently displayed several times. The higher the current display voltage, the fewer the number of movements.

3. After the voltage adjustment is completed, press the right button on the right and loosen it after 2 seconds. At this time, you can exit the voltage calibration mode. All parameter settings are automatically powered off and saved.

Note: You only need to calibrate this method of adjustment to get accurate voltage values ​​on the entire voltage range. This function is designed to meet your higher accuracy requirements. Please use it with confidence.
