LM2596 DC DC Step Down Converter Voltage Regulator Voltmeter 4-40V to 1.2-37V Buck Adjustable Adapter Power Supply Module with LED Display
Features:
1. Original LM2596, large chip, frosted surface, output short circuit protection, high current 3A.
2. The voltmeter can be turned off, and it can be easily achieved by pressing the left button when it is not needed.
3. With terminals, it is easy to use without a soldering iron, and the soldering wire connection points are reserved.
4. Touch the button to switch the measurement input or output voltage, and there is an indicator light to show which voltage is being measured, and save the settings, even if the power is turned off and then turned on again.
5. With voltmeter display and the voltmeter can be self-calibrated. Using a more advanced voltage microprocessor, the error of the voltmeter 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).
Specifications:
Input voltage 4.0~40V. (The input voltage must be more than 1.5v higher than the output voltage)
Adjustable output voltage range 1.25V~37V continuously adjustable. (The input voltage must be 1.5V higher than the output voltage)
The output current is 3A, and it is recommended to use it within 2.0A. For large currents, heat dissipation needs to be strengthened.
The output power is 20W, if it exceeds 15W, please strengthen the heat dissipation.
High conversion efficiency, with an average of 88% (efficiency is related to input, output voltage, current, and voltage difference)
With reverse connection protection, reverse connection does not burn
With overheat protection and short circuit protection
Application range:
This module can be used in the step-down field where the input voltage is higher than the output voltage, such as batteries, power transformers, DIY adjustable regulated power supplies, 24V car pen power supplies, industrial equipment step-down, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V, etc.
On-board voltmeter self-calibration method:
1. When the on-board voltmeter displays the output voltage, press and hold the right button for 2 seconds and then release, the voltmeter and the output voltage indicator "OUT" flash simultaneously, and enter the output voltage adjustment mode; When inputting voltage, press and hold the right button for 2 seconds and then release, the voltmeter and the input voltage indicator "IN" flash simultaneously, and enter the input voltage adjustment mode at this time;
2. Touch the right button, the voltage will increase by one unit, and touch the left button, the voltage will decrease by one unit; since the voltage value of one unit is less than 0.1V, you need to press 1-5 times continuously to see the voltmeter Changed by 0.1V, the specific number of times of pressing the button depends on the currently displayed voltage value, the higher the current displayed voltage, the less the number of times of pressing;
3. After the voltage adjustment is completed, press and hold the right button for 2 seconds and release it, then you can exit the voltage calibration mode, and all parameter settings are automatically saved after power off.
Note:
1. Due to the light and screen difference, the item's color may be slightly different from the pictures.
2. Please allow 1-3cm differences due to manual measurement.
Package Included:
