2 PCS Electronic Accessories: 1 x Rheostat & 1 x Adjustable Wire Wound Resistor Control the electrical resistance of a circuit without interrupting the flow of current. The rheostat is consisted of ceramic core and a resistive wire wrapped to form a toroid coil with a wiper axle. Can be used widely as light dimmers and motor speed control, is applicable for arc lamps, pumps, fans and blowers, respirators, dental and model trains or other applications that require high voltage and current. Product Name: Adjustable Wire Wound Resistors Type: Adjustable 200W rated power, 100 Ohm resistance, tubular shaped body, variable resistors with one adjustable band. Metal wire is wound on the ceramic tube coated with non- material, good dissipation, high stability and . The wirewound resistor can be widely used in power supply, transducer, elevator, audio and high requirement equipment industry.
