USB electronic load module aging resistance charger mobile power supply 5V test 3A/2A/1A current
Overview
According to Ohm's law (voltage/resistance value = output current), the USB discharge load device is designed to load different power resistance values ??through the control of the above two switches, and three kinds of current aging can be obtained, namely 1A/2A/3A. On-board There are corresponding indicator lights and power indicator lights of different resistances, which are clear and clear. It is easy to use and can test the power bank mobile power charger for aging test.
Features
5V USB test
Three gears optional
Indicator light display status
3. Hardware introduction and description
Board size: 67*22mm
4. Instructions for use
The USB plug is inserted into the 5V output interface. Because of the maximum power limit of the resistance and the resistance, it cannot be connected to the fast charging interface above 5V.
After power on, the power indicator D1 will light up.
Switch S1 to "ON" block, D2 lights up, the resistance of 4R7 starts to work, and the current is about 1A.
Switch S2 to "ON" block, D3 lights up, the resistance of 2R5 starts to work, and the current is about 2A.
If S1 and S2 are turned to "ON" at the same time, the two resistors work and the current is about 3A.
Notice!
Because a large amount of current is consumed by the work of the resistor to generate heat, the resistor will be hot, so be careful not to touch the resistor with your hands to avoid burns.
