This is LM2596 2A Buck Step-down Power Converter Module DC 4 ~ 40 to 1.3 ~ 37V, it comes with a built-in voltmeter display and uses an advanced microcontroller.

Together with its high precision multi-turn potentiometer, this means any desired output voltage within its supply range can be set without the need for an external voltage meter. The module also boasts a very high operating range with a DC input supply range of 4 ~ 40V and an adjustable output range of 1.3 ~ 37V.

Output voltage calibration steps:

Step 1: Adjust the right button so that “OUT” LED lighted, the voltmeter shows the value of output voltage; Press the right button for more than 2 seconds, release, voltmeter and “OUT” LED flashes in synchronization so that you enter the output voltage calibration mode.

Step 2: Press the right button (normal speed), the voltage value is adding up a unit; Press the left button, minus a unit; Due to a unit is less than 0.1V, the minimum voltage display to 0.1V, so you need to continuously press 1-5 times to see the voltmeter change 0.1V, how many times voltmeter change 0.1V by pressing the key, depending on the current display voltage, the higher the voltage, the fewer the number of press.

Step 3: Press the right button for more than 2 seconds, release, to exit the output voltage calibration mode. All parameters set to automatically power down to save.

Step 1: Adjust the right button so that “IN” LED lighted, the voltmeter shows the value of input voltage; press the right button for more than 2 seconds, release, voltmeter and “IN” LED flashes in synchronization so that you enter the input voltage calibration mode.

Steps 2 and 3, consistent with the output voltage calibration method.

The 10A DC-DC Step-down Adjustable Constant Voltage Module can be used to get adjustable output voltage ranges from 1.5V to 35V. The module provides a wide range of current output up to 10 A. With heat sink mounted it can easily manage to run high power application continuously (provided that for continuous high power output you need to use a cooling fan on the heat sink).

The Module is made from a dedicated benchmark IC and high-precision current sensing resistor, proving a more stable constant current, (when 20°C to 100°C constant current 1A, temperature drift less than 1%); and therefore it is particularly most suitable for LED driver applications. The output current of the module can be raised up to 10A(for continuous use it is recommended up to 8A with additional cooling fan).

To enhance the stabilization in output voltage has four high-frequency capacitance which gives the lower output ripple. Double heat sink design provides easy and fast heat dissipation. MOS Schottky diode independent heat sink, which heat dissipation is good, and won’t affect each other. Also using large size Sendust Core and double pure copper wiring, improve working efficiency, reduce fever.

The module has onboard 3296 multiturn potentiometers for high accuracy voltage and current regulation to provide good stability. As voltage and current are adjustable, it gives very easy to use at multiple Application such as battery charging, LED Driver power supply, Vehicle Power Supply, etc which makes the module Multipurposeand hence this module is always in demand from our maker because of its wide range of application and low cost.

Applications:

1. High-power LED driver.
2. Lithium battery(or lead accumulator) charge.
3. Vehicle-mounted power supply.
4. Low voltage system power supply.
5. 6V, 12V, 14V, 24V battery charge.
6. On-board laptop power supply.
7. regulated power supply.
8.Low voltage power supply system.

Note: If the module temperature exceeds 65ºC, please add a cooling fan,  (It be used at room temperature without a fan)

Keeping track of contemporary market development, we are devotedly occupied in providing an extensive series of DC To DC Boost Converter.
