REE200

Rotary Potentiometers, Rheostats

REE200 application fields mainly include motor speed control, voltage regulation, thermostat, computer servo system, sound volume control, etc. Rheostats may also be used in the same application field to adjust the electrical current. Other applications include domestic heating or electrical window blinds, where a smooth adjustment of the level of comfort is important.

The working principle of the REE200 is based on the principle of a potentiometer. A potentiometer is a three-terminal device, consisting of a resistive element and two contacts, the wiper arm and the end contacts. As the wiper arm is moved over the resistive element, it changes the resistance between the two end contacts. The REE200, like other potentiometers, has an adjustable range of resistance. It also has a maximum resistance which is set at the factory. This maximum resistance is referred to as the stop point and it is used to control the maximum voltage or current that will be supplied to the load.

When used to adjust the speed of a motor, the REE200 is connected to the motor in such a way that as the wiper arm is adjusted, the voltage applied to the motor increases or decreases. This, in turn, increases or decreases the speed of the motor. The stop point of the REE200 can be adjusted to limit the maximum voltage the motor will receive, thereby regulating the speed. Similarly, the REE200 can be used to control the voltage in other applications such as computer servo systems, sound volume control, and domestic heating or electrical window blinds.

Rheostats have a similar working principle to the REE200, except that instead of applying a variable voltage to the load, the rheostat adjusts the current. The rheostat is connected in series with the load, which varies the current flowing in the circuit. As the rheostat is adjusted, the current through the load changes. This principle is useful for controlling the amount of current supplied to domestic heating or electrical window blinds.

In conclusion, the REE200 is a three-terminal device that is used to control the voltage applied to a load. It works by varying the resistance between two of its terminals. Rheostats are similar devices that vary the current instead of the voltage and are useful for controlling the amount of current applied to a load.
