USB Electronic Load Aging Resistance Charger 3A / 2A / 1A

USB Electronic Load Aging Resistance Charger 3A / 2A / 1A Charger Indicator Discharge Charging Mobile Power Test

Overview:

According to's law (voltage/resistance value=output current), the USB discharge load device is designed to load different power resistance values through the two switches above, and 3 types of current aging can be obtained, which are 1A/2A/3A. Onboard Corresponding indicator lights and power indicator lights with different resistances are clear. It is easy to use and can be used for aging test of mobile power charger.

Features:

1. 5V USB test

2. Three gears can be selected

3. The indicator shows the status

Hardware introduction and description:

Board size: 67*22mm

Weight: 14g

Instructions for use:

The USB plug is plued into the 5V output interface. Because of the resistance value and the maximum power limit of the resistor, it cannot be connected to the fast charging interface above 5V.

Ar power on, the power indicator D1 will light up.

Switch S1 to the "ON" gear, D2 lights up, the 4R7 resistor starts to work, and the current is about 1A.

Switch S2 to the "ON" gear, D3 lights up, the 2R5 resistor starts to work, and the current is about 2A.

If S1 and S2 are switched to the "ON" gear 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 working heat of the resistor, the resistor wilet hot. Take special care not to touch the resistor with your hands to avoid burns.
