Rotary Potentiometers, Rheostats

The 91U1A-T22-B17L is an electrical component that is categorized as a Rotary Potentiometer and Rheostat. It consists of a three terminal device, which is connected to a contact-slider that is then connected to the resistance element when it rotates. This device has a maximum rated power of 30 W/K ohm with a maximum operating voltage of 440 VAC. There is also a Maximum angular rotation of up 300 degrees, and Operating Temperature Range -25℃ to +65℃. The device controls the flow of electric current in a circuit by either a varying or fixed resistance, depending on the application.

Application Field

Rotary Potentiometers and Rheostats are used in a variety of applications, the 91U1A-T22-B17L in particular is mostly used for lighting and heating applications. In lighting applications, the 91U1A-T22-B17L is used to control the brightness of lights among other things. In heating applications, the 91U1A-T22-B17L can control the temperature of a space by regulating the power of heating elements. Another example where this device is used is for dampers in air conditioners, where the 91U1A-T22-B17L is used to regulate the flow of air.

Working Principle

The 91U1A-T22-B17L functions primarily on the basis of the resistance-temperature effect. As the contact-slider is moved along the resistance element, the resistance of the circuit is effectively modified. This is the "potentiometer" part of the device, where the resistance is proportional to the slider position. The "rheostat" part of the device is where the contact-slider is placed at one end of the resistance element, and current is adjusted by changing the position of the contact-slider. The 91U1A-T22-B17L is used in either a potentiometer or rheostat form, depending on the application.

Conclusion

In summary, the 91U1A-T22-B17L is a Rotary Potentiometer and Rheostat used for various applications such as in lighting, heating, and air conditioning. It functions by changing or modifying the resistance in a circuit according to the position of the contact-slider along the resistance element. It has a Maximum rated power of 30 W/K ohm with a maximum operating voltage of 440 VAC. There is also a Maximum angular rotation of up 300 degrees and an Operating Temperature Range of -25℃ to +65℃.
