WXD3-13 is a precision multi-turn, (10-turn) wire-wound potentiometer with a power of 2W. This product is used in telecommunication, electrician, electronic instruments and equipment. .
Used as a voltage divider: a potentiometer is a continuously adjustable resistor. When the potentiometer's handle or slide is adjusted, the moving contact slides on the resistor body. At this time, the output terminal of the potentiometer can obtain the input voltage which has a certain relationship with the applied voltage of the potentiometer and the rotation angle or stroke of the movable arm.
Used as a varistor: When the potentiometer is used as a varistor, it should be connected as a two-terminal device, so that a smooth and continuously changing resistance value can be obtained within the stroke range of the potentiometer.
Used as a current controller: When the potentiometer is used as a current controller, one of the selected current outputs must be a sliding contact terminal.
