Adjustable 3/15 Current USB Load Resistor Discharge

Support QC2.0(5V/12V/20V), Compatible QC3.0(3.8~12V,+/-2 Step), Android BC1.2(5V), 5V voltage range and MTK-PE 5V/7V/9V/12V, etc.Fast charging preure range

K1=20Ohm/10W K2=10Ohm/10W K3=4.7Ohm/10W K4=2.2Ohm/10W Support QC2.0(5V/9V/12V/20V), Compatible QC3.0(3.8~12V,+/-2 Step), Android BC1.2(5V), 5V voltage range and MTK-PE 5V/7V/9V/12V, etc.Fast charging preure A designed according to the principle of's law and through the resistor in parallel through a different switch, can produce 15 kinds of resistance of a new USB electronic load resistance discharge, when all the switch opens, is 2.2/10W, 4.7/10W, 10/10W, 20/10W 4 kinds of resistance in parallel at the same time, in 5V voltage almost can produce 4A discharge current. The actual current size, please according to's law: I = U/R Resistor in parallel calculation formula: R=1/(1/R1+1/R2+...+1/Rn) K1=20Ohm/10W K2=10Ohm/10W K3=4.7Ohm/10W K4=2.2Ohm/10W

Load device is working, winding resistance caused by large current, will produce very, very high temperature, therefore in the proce of use, and just use the finished in a short period of time, absolutely can't human exposure golden metal radiator parts, to avoid the scald!Nor to flammable it contact tester, in order to avoid the fire!In use proce must be highly vigilant! Considering the particularity of heat resistance, the initial use of electricity ar a period of time will appear a few smoke and smell, because outside the paint contains very little moisture, high temperature electric heating, moisture eates form the phenomenon of smoke, produce peculiar smell by high temperature baking paint outside phenomenon, completely disappear ar using for a period of time.This phenomenon is inevitable, belongs to the normal situation, do not have to worry about load tester can damage, please be aured that use. The load application Can be convenient to test mobile power charging treasure, mobile phone charger, USB power output current is such as to amount to mark, so long as connect USB above.And can do it for mobile power supply and USB power adapter aging test, aging test discharge resistance will be hot, temperature is controlled in 80 ~ 85, please pay attention to prevent hot
