Product Application

1. DIY a regulated power supply with an input of 5V and an adjustable output of 5-35V.

2. To power your electronic devices, the output value can be set according to your system voltage. For example, using a 3.7V lithium battery to boost 5V as a portable power bank, or using 7.4V or 12V to boost 19 for laptop power supply.

3. As a car power supply, it provides power for your laptop, PDA, or various digital products.

Product Instructions

1. Adjust the right-click button to turn on the "OUT" indicator light, and the voltmeter will display the output voltage; Press and hold the right button for more than 2 seconds, then release it. The voltmeter and "OUT" indicator light will flash synchronously, and you will enter the output voltage display calibration mode.

2. Short press the right button once (at normal speed) to increase the voltage value by one unit. Short press the left button to decrease the voltage value by one unit; Due to the voltage value of a unit being less than 0.1V, the minimum displayed voltage on the voltmeter is 0.1V. Therefore, you need to press the button continuously 1-5 times to see the voltmeter change by 0.1V. The specific number of times the button is pressed continuously depends on the current displayed voltage. The higher the current displayed voltage, the fewer times it is pressed.

3. After adjusting the output voltage, press and hold the button on the right for more than 2 seconds, and then release it to exit the output voltage display calibration mode. All parameter settings are automatically saved upon power failure.

Input voltage display calibration:

Step 1: Right click to turn on the "IN" indicator light, and the voltmeter will display the input voltage; Press and hold the right button for more than 2 seconds, then release it. The voltmeter and "IN" indicator light will flash synchronously, and you will enter the input voltage display calibration mode.

2. 3. Consistent with the calibration method for output voltage display.

This product undergoes at least three inspections before shipment, and the voltage display accuracy is guaranteed to be within 0.1V. The calibration function is designed to meet your higher accuracy requirements, so please feel free to use it.
