Steps:
1. Connect the input terminal to DC3-38V power supply, pay attention to the positive and negative poles.
2. Use a digital multimeter to measure whether the voltage at the output terminal matches the load you want to connect. If it does not match, you can adjust the voltage potentiometer. After the voltage is adjusted, adjust the current potentiometer to the maximum, and turn the potentiometer clockwise to the top. Maximum voltage and current.
3. After adjusting the voltage and current, connect the load you want to connect to the output terminal, paying attention to the positive and negative poles of the power supply.
Note:
1. All wiring-must be done with the power supply disconnected!
2. The input terminal can also be lowered when the voltage is lower than 5V, but the indicator light will not light up, and it will light up normally when it is above 5V.
3. The factory default is 5V output. If the voltage and output current are adjusted, the positioner will have a few more turns to respond.
4. In actual use, it will heat up severely according to the size of the load. When the load is above 3A, the normal temperature is within 100 degrees of heat, and it can be used with confidence.
5. If the long-term load is above 3.5A, it is recommended to use a fan to cool the module to extend its life.
6. During the charging process, multiple lights will be on at the same time, indicating that the mode is being transferred, which is a normal phenomenon.
7 The input terminal must use an adapter or a switching power supply, and the transformer is not currently supported.
