1PCS USB Resistor Dc Electronic Load Tester With Switch 5V

USB load resistor electronic adjustable voltage 3 current industrial High power discharge resistance battery capacity tester 5V 1A/2A/3A with switch 1A / 3A switchable, 2A / 3A switchable, Warm reminder: 1. The switch is only used to change two gears, not adjustable! For example, 1a3a, can only switch 1a and 3a, can not measure 2A! 2. The resistance of the load is only designed for 5V, not used to test other voltage such as 9V, 12V equipment! 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 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=4.7Ohm/10W , K2=2.2Ohm/10W Package included: 1Pc

Product Description Switch and usb interface design Color:Green Rated Power:5W-10W Technology:Ceramic Composition Resistance:1A-2A Size:72mm x 17mm(approx.) Note: When using this discharge resistor need to be very careful, touching is forbidden in case of burning. Also, please do not put flammable substances nearby when using it, and avoid direct contact with the heat resistance of the desktop, so as not to scorch the desktop. It's normal when welding resistance may occur heated smoke or odor phenomenon. New products can freely be switched with a switch, very convenient and easy to use. USB load resistance, is mainly to do discharge test, if the charger or mobile power supply output current is 2A, load meter power is 5V * 2A = 10W, if the output current is 1A, then the power load is 5V * 1A = 5W. Package includes: 1 x USB Discharge load resistor
