DC-DC Adjustable Step-Down Power Supply Module LM2596 Voltage Regulator With Voltmeter Digital Display 3.3V5V12VItem NO.: MK01598

DC-DC Adjustable Step Down Power Supply Module

Product Features:

1. With power indicator light

2. With button adjustment output voltage function

a. When ensuring that the input voltage is between 7-36V and the output voltage is below 10.0V, it can be adjusted at 0.02V. When the output voltage is greater than or equal to 10V, it can be adjusted with a variation of 0.1V. (It can actually achieve 0.02V due to display reasons)

b. 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.

3. With voltmeter display and advanced microprocessor, the error of voltmeter is ± 0.05V, the input voltage range is 0~40V, and the output voltage range is 0~35V (note: to ensure the accuracy of program control and display, please ensure that the input voltage is above 7V). Each meter is shipped with a built-in accuracy calibration program in this module.

4. Short press the IN/OUT button to switch between measuring input or output voltage, and an indicator light displays which voltage is being measured, and saves the settings. Even if the power is turned off and turned on again, it is still the last set value.

5. The display of the voltmeter can be turned off. When the display is not needed, long press the ON/OFF button to easily achieve. This setting implements the power down save function.

6. The output voltage can be turned off. When it is necessary to turn off the output voltage, press the ON/OFF button briefly and release it to achieve the shutdown of the output voltage. If you want to start, you need to press the ON/OFF button briefly and release it to start the output voltage. When the output terminal is loaded, the output voltage will quickly drop to 0. If there is no load, the output voltage will slowly drop to 0 V through the sampling resistance. This setting implements the power down save function.

7. Equipped with wiring terminals, it is easy to use without soldering iron, and retains the soldering wire connection points.

8. The normal and stable working current is 2A, and the maximum output current can reach 3A (if the output exceeds 2A, heat dissipation needs to be strengthened)

9. Adopting an internal oscillation frequency of 150KHz, it belongs to the second generation switch voltage regulator, with low power consumption and high efficiency

10. Equipped with overheating protection and short circuit protection functions.

Special Attention:

1. The output voltage control range is between 0.5V and 35V, with 35V being the limit output voltage. It is recommended to not exceed 32V when using.

2. The minimum output voltage of this module is 0.5V. The lower the output voltage in the no-load state, the higher the voltage drift. If the customer requires a minimum voltage, a 200-500 ohm resistor needs to be connected in parallel at the output end.

3. If a current output of 2.1A~3A is required, this module needs to strengthen heat dissipation. If heat dissipation is not strengthened, long-term operation may cause damage to the module.
