LUJIAYA 150w 300w 500w BC1 high Power rheostat,rotary variable wire wound resistor, disc shape,adjustable resistor, (Size : Max R-100 ohm, Color : Max power 500W)

1.The sliding varistor is one of the commonly used devices in electricity, and its working principle is to change the resistance by changing the length of the resistance wire connected to the circuit, so as to gradually change the size of the current in the circuit. 2.Made of materials to last longer.Exquisite workmanship, accurate installation position, easier and simpler to replace and disassemble 3.Rotary manual operation, the resistance value can be adjusted, it can be naturally cooled, the surface is glazed, high power, strong overload capability and high temperature resistance. 4.It can be used widely as light dimmers and motor speed control, is applicable for arc lamps, pumps, fans and blowers, , model trains or other applications that require high voltage and current.
