This power supply is very convenient to use. You only need to plug in the USB or micro USB to output an adjustable voltage from 1.2V to 24V, and the power is 3W. It is very suitable for technical engineers to develop, debug instruments, and after-sales engineers travel and repair to supply power to instruments. Very convenient.1. It is very convenient to use, plug in USB or micro USB to output an adjustable voltage of 1.2V-24V2. One key to turn off the output3. The digital tube can be turned off4. Use multi-turn precision adjustable potentiometer to adjust5. The state before power failure is storedSpecial Note1. Connecting the LDO type voltage regulator element to the output will cause interference and increase the ripple, which may burn the chip.2. This product is not a high-power power supply, please use it within the range.Input voltage: 3.5V-12VOutput voltage: 1.2V-24VOutput Power: Output voltage 1.2V-2V, use within 2W Output voltage 2V-20V, use within 3WOutput voltage 20V-24V, use within 2.5WOutput power = output voltage × output current
