Stead 400R+400R 100W Wire Wound Potentiometer Resistor

It is a Stead 400R+400R 100W Wire Wound Variable Double Rotary Potentiometer. Its resistive part is rotary. In which two wiper in this type is mounted with a single spindle on a shaft and the movement of this shaft will change the length and resistance. Basically it is a variable or adjustable double rotary Potentiometer. It works as when rotate the spindle then both the wiper rotates in same direction and resistance will be vary.A rheostat is a variable or adjustable resistor that can control the electrical resistance of a circuit without interrupting the current flow.It isa two hollow circular each of having three connections screw terminal.The ceramic and the wire wound assembly over it are covered by silicone. A resistive wire is wrapped to form a toroid coil with a wiper that slides along the coil’s surface. There are three screw terminal when we rotate the wiper in clock-wise direction resistance increases and rotate in anti-clockwise direction resistance decrease . It has a special feature that upper Potentiometerbetween middle and right screw terminal drive some amount of resistance and lower rheostat’s between middle and left screw terminal drive remaining resistance . Both of rheostat when between left or right and middle screw terminal drive total resistance. It is constructed with a ceramic core. High voltage and current are frequently required in Applications.
