2X10W USB Resistor Electronic Load DC Switch Tester Resistance Moudule Item Description Description: A designed according to the law of Ohm's law and through parallel resistance through a different switch, can produce 3 types of resistance of a new electronic USB discharge load resistance, when all the switch opens, it is 2.2 ohms / 10w, 4.7 ohms / 10w, 2 kinds of parallel resistance at the same time, In 5v voltage almost able to produce 3A discharge current. The actual current size, please according to the law of ohms: I = U / R
Parallel resistance calculation formula: R = 1 / (1 / R1 + 1 / R2 + ... + 1 / Rn)
K1 = 4.7Ohm / 10w, K2 = 2.2Ohm / 10w
Load device is running, winding resistance caused by large current, it will produce very, very high temperature, so in the process of use, and just use the finished in a short time, absolutely can not human exposure to golden metal radiator parts, in order to avoid sunburn! nor to flammable materials to contact tester, In order to avoid fire! In use process must be highly vigilant!
Considering the particularity of heat resistance, the first use of electricity after a period of time is displayed a white pair of smoke and odor, because outside the paint contains very little moisture, high temperature electric heating, moisture evaporates form the phenomenon of white smoke, produce particular smell from high temperature of cooking paint outside phenomenon, completely disappear after using for a period of time. this phenomenon is inevitable, belongs to the normal situation, no need to worry about load tester capable of damage, please be assured that the use
Application load:
It can be convenient to test mobile power charging treasure, mobile phone charger, USB power output current is such as for quantity to mark, so long as USB connect above. and able to do it for the mobile power supply and USB power adapter aging test, aging test of exhaust resistance will be hot, the temperature is controlled in 80 ~ 85, please pay attention to prevent it from hot
