Applications:
WXD3-13 is a precision multi-turn (10 turns) wire-wound potentiometer with power of 2W.It is suitable for use in telecommunications, electrics, electronic instruments and equipment. lt can be used for distribution cabinet, precision regulation of DC or low-frequency voltage and current.
Used as voltage divider:
A potentiometer is a continuously adjustable resistor, When adjusting the handle of the potentiometer, the moving, contact slides on the resistor body.At this time, the output end ofthe potentiometer can be obtained with the potentiometer external voltage and the movabe arm rotation Angle or stroke into a certain relationship of the output voltage.
Used as a rheostat:
Potentiometer used as a rheostat, it should be connected to both ends of the device, sucha flower potentiometer within the range of travel, can obtain a smooth continuous changeof resistance value.
Used as a current controller:
When a potentiometer is used as a current controller, one of the selected current outputsmust be a sliding contact outlet.
