Features:
1. Adopting an internal oscillation frequency of 150KHz, it belongs to the second-generation switching voltage regulator, with low power consumption and high efficiency.
2. Equipped with a power indicator light and a button to adjust the output voltage function.
3. The voltmeter display can be turned off, and it can be easily achieved by long pressing the ON/OFF button when no display is needed. This setting implements the function of power-off saving.
4. With wiring terminals, it can be easily used without a soldering iron, and the solder wire connection points are retained.
5. It has overheat protection and short circuit protection functions, with a normal and stable working current of 2A, and a maximum output current of up to 3A (if the output exceeds 2A, heat dissipation needs to be strengthened).

Input voltage: DC7~36V
Output voltage: 0.5V~35V
Current: The stable working current is 2A, and the maximum output current can reach 3A (if the output exceeds 2A, heat dissipation needs to be strengthened)
Oscillation frequency: 150KHz
Digital display: 3 digits
Digital display color: red
Size: 56mm * 41mm
Function Introduction:
1. When ensuring that the input voltage is between 7-36V and the output voltage is below 10.0V, it can be adjusted by 0.02V. When the output voltage is greater than or equal to 10V, it can be adjusted with a variation of 0.1V. (Actually, it can achieve 0.02V due to display reasons)
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.
3. With a voltmeter display, using advanced microprocessors, the voltmeter error is ± 0.05V, the input voltage range is 0-40, and the output voltage range is 0-35V (note: to ensure the accuracy of programming and display, please ensure that the input voltage is above 7V). Each meter is manufactured through a built-in precision calibration program in this module.
4. Short press the IN/OUT button to switch between measuring input or output voltage, and there is an indicator light indicating which voltage is being measured, and the setting is saved. Even if the power is turned off and turned on again, it is still the last set value.
5. The output voltage can be turned off. When it is necessary to turn off the output voltage, short press the ON/OFF button and release it to turn off the output voltage. If you want to turn it on, you need to press the ON/OFF button briefly and then release it to turn on the output voltage. When the output terminal is loaded with a large load, the output voltage will quickly drop to 0. If there is no load, the output voltage will slowly drop to 0V through the sampling resistor. This setting implements the function of power-off saving.
Operating instructions:
1. Short press and release the IN/OUT button to switch between input and output voltage display functions.
2. Short press and release the ON/OFF button to turn off the output. If a large external load is connected, the output will quickly drop to 0V. If the load is not connected, the output will slowly drop to 0V.
3. Long press the ON/OFF button to turn off and on the digital display.
4. Short press the "+" button to enter the output voltage setting mode, flash the OUT indicator light and display the set output voltage. If it is below 10V, it can increase by 0.02V per grid, and if it is above 10V, it can increase by 0.1V per grid. Long press the "Add" button to achieve a rapid increase in voltage. After releasing, press the no add/subtract button for 2 seconds to automatically exit the output voltage setting mode.
5. Short press the "-" button to enter the output voltage setting mode, flash the OUT indicator light and display the set output voltage. If it is below 10V, it can be reduced by 0.02V per grid, and if it is above 10V, it can be reduced by 0.1V per grid. Long press the "decrease" button to achieve a rapid decrease in voltage. Press the no add/subtract button for 2 seconds after releasing to automatically exit the output voltage setting mode
Special attention:
1. The output voltage control range is between 0.5V and 35V, with 35V being the maximum 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 more voltage will float. If the customer requires a minimum voltage, a resistor of 200-510 ohms 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 will cause damage to the module.
