Specification:Rated Power: 5W-10W.Technology: Ceramic Composition.Resistance: 1A-2A.Type: Fixed Resistor.PCB size: approx. 7.3*1.8*1cm/2.87*0.7*0.39'' Description:1.There is a 1A/2A current button to switch 1A or 2A current discharging.2.Work voltage is 5V, power is 5W-10W, switching the button to change resistance and current.3.Pay attention to the high temperature generated in the work process of load resistance, please don't touch to avoid scald and stay away from flammable items.4.Working with indicator light, switch button marked current value, to indicate the current mode at present. Steady light means reaching up to standard output rating, off or flash means the power supply is less than rated output standard.5.Easy to install and easy to disassemble
