LC-USB-Load-15W is a electronic load, the purpose of constant current input is achieved through the power consumption of the transistor, the heat of the heater and the fan.
1>.Adjust power consumption at will by potentiometer
2>.The fan automatically turns on when the board temperature reaches 40°C
3>.Quickly release the accumulated heat on the heat sink for long-term stable operation
1>.Product name: USB electronic load
3>.Input voltage: 5V
4>.Input current: 0~3A
5>.Power consumption: 15W(Max)
6>.Work Temperature: -25℃~85℃
4>.Work Humidity: 5%~95%RH
4.Instructions for use:
1>.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 USB ammeter or multimeter in series;
2>.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;
3>.Similarly, if the potentiometer is turned counterclockwise, the minimum power consumption is 0;
4>.The required test power consumption can be adjusted by a potentiometer;
5>.The fan turns on automatically at 40°, be careful not to touch the fan blades.
