DC Adjustable Step-Down Power Supply Module LM2596 Voltage Regulator With LED Voltmeter Display Digital 3.3V 5V 12V Type G

DC-DC adjustable step-down power supply module LM2596 voltage regulator with voltmeter display digital display 3.3V 5V 12V

Features:

With power supply indicator output voltage function.

1. Ensure that the voltage input can be between 7-36V. When the output voltage is lower than 10.0V, it can be adjusted by 0.02V. When the output voltage is greater than or equal to 10V, it is adjustable by 0.1V. (actually 0.02V can be achieved because of the display)

2. The output voltage control range is between 0. 5V and 35V. If the set output voltage exceeds the input voltage, the output will only be equal to the input.

With voltmeter display, using advanced microprocessor, voltmeter error soil 0.05V, input voltage range 0~40,

Output voltage range 0~35V (Note: To ensure the accuracy of program control and display, please ensure that the input voltage is above TV). Each meter is factory-installed with a precision calibration procedure built into the module.

● Short press the IN/OUT button to switch the measurement input or output voltage, and the indicator light indicates that it is being measured.

Which voltage is the voltage and the settings are saved, even if it is powered off and then turned on, it is the last setting.

● The voltmeter display can be turned off. When the display is not needed, long press the 0N/0FF button to easily implement it.

Set to implement the power save save function.

●The output voltage can be turned off. When the output voltage needs to be turned off, press the 0N/0FF button and release it.

The output voltage can be turned off. If you want to turn it on, you need to press the 0N/0FF button and release it.

When the output voltage is turned on and the output is loaded with a large load, the output voltage is quickly reduced to zero. If there is no load, the output voltage will slowly drop to oV through the sampling resistor. This setting implements the power-down save function.

●With terminal block, no soldering iron can be used conveniently, and retain the wire bond point

● Normal stable working current is 2A, the maximum output current can be as high as 3A (if more than 2A output, need to add

Strong heat dissipation).

●Using 150Hz internal oscillation frequency, it belongs to the second generation switching voltage regulator, with low power consumption and high efficiency.

● With overheat protection and short circuit protection

Introduction (2) Operating Instructions

1. Short press and release the IN/OUT button to switch the input/output voltage display function.

2. Short press to release the ONV/OFF button to turn off the output. If the external large load output will drop to 0V quickly. If the load output is not connected, it will slowly drop to oV.

3. Press and hold the OW/OFF button to turn the digital tube display off and on.

4. Short press the "+" button, it will enter the output voltage setting mode, flashing our indicator light and display the set output voltage. Below 10V, it can increase by 0.02V per division, and above 10V, increase by 0.4% per division. Press and hold the “Add” button to increase the voltage quickly. After 2 seconds of release, there is no addition or subtraction button press, and the output voltage setting mode is automatically exited.

5. Short press the “_” button to enter the output voltage setting mode, flash the ouT indicator and display the set output voltage. Below 10V, it can be reduced by 0.02V per division. Above 10V, it is reduced by 0.1V per division. Press and hold the "Down" button to achieve a rapid voltage reduction. After 2 seconds of release, no button is pressed or decremented to automatically exit the output voltage setting mode.
