The answer is as follows: The methods for adjusting the DC-DC PSU are as follows:
1. Input voltage regulation: Rotate the potentiometer to adjust the input voltage, generally 2.5-25V.
2. Output voltage regulation: Rotate potentiometer to adjust the output voltage, generally 2-25V.
3. Output current adjustment: Rotate potentiometer to adjust the output current, generally 1-3A.
4. Output voltage stability adjustment: rotating potentiometer to adjust the output voltage stability, generally ±0.5%.
5. Input voltage protection: When the input voltage exceeds the set value, the module will automatically cut off the output to protect the load and the module.
6. Output current protection: When the output current exceeds the set value, the module will automatically cut off the output to protect the load and module.
7. Short circuit protection: When the load is short circuit or the output is short circuit, the module will automatically cut off the output to protect the load and module.
8. Overtemperature protection: When the internal temperature of the module is too high, the module will automatically cut off the output to protect the load and the module.
Regarding this problem, the adjustment method of DC-DC adjustable booster voltage regulator power module is as follows:
1. Connect the input and output ports on the power module, and then connect the power supply.
2. Adjust potentiometer: Usually the power module will have a potentiometer, you can adjust the output voltage by rotating the potentiometer;
3. Test output voltage: Use a multimeter or voltmeter to test whether the output voltage meets the needs, if it does not meet the needs, you can continue to adjust the potentiometer;
4. Voltage regulation: In the case that the output voltage has been adjusted, the voltage regulation can be used to adjust the output current, usually by rotating the potentiometer.
Note that when adjusting the power module, you should first adjust the output voltage to the required voltage range, and then adjust the voltage. At the same time, pay attention to the maximum output current and load capacity of the power module to avoid exceeding the rated parameter range of the power module.
This can adjust the potentiometer on the circuit board to adjust the output voltage, quite convenient.
