How to detect the current of the power adapter
time2019/05/11
- If you want to detect the full load rated output current of the power adapter, look at the low voltage output voltage/current value marked by the adapter and calculate the power value = voltage X current.
If you want to detect the full load rated output current of the power adapter, look at the low voltage output voltage/current value marked by the adapter and calculate the power value = voltage X current. Then find a load resistor with twice the power value and the corresponding current value/voltage value. Connect the power supply as shown below to observe the performance of the meter and the adapter.
1. There is a caliper current detection meter.
2. Borrow the terminal board, measure the voltage with a series of sampling resistors, and convert it into a current.
3. Borrow the terminal board and directly string the multimeter (AC current file).
