Product selling point
1: Input voltage 5V (access via usb)
2: Input current 0~3A, maximum power consumption 15W
3: When the board temperature reaches 40°, the fan is automatically turned on.
4: The power consumption can be adjusted by the potentiometer.
5: Small size, easy to carry
The 15W USB electronic load consumes energy through transistors, heat sinks and fans to dissipate heat to achieve the purpose of constant current input.
The input voltage is fixed at 5V, the maximum input current can reach 3A, and the maximum power consumption is 15W. The power consumption can be adjusted at will through the potentiometer.
The fan automatically turns on when the board temperature reaches 40°.
Quickly release the accumulated heat on the heat sink for long-term stable operation.

Instructions for use
Insert the usb power supply device, the red LED light of the board lights up, indicating that the power supply is normal. The input current can be tested by a usb ammeter or a multimeter in series. Turn the potentiometer clockwise and you can hear a "click" sound, indicating that it has reached the end. At this time, the input constant current is about 3A, and the power consumption reaches the maximum value of 15W.
Similarly, if the potentiometer is turned counterclockwise, the minimum power consumption is 0.
The required test power consumption can be adjusted by a potentiometer.
The fan turns on automatically at 40°, be careful not to touch the fan blades.
