Rotary potentiometers and rheostats are classic electrical devices used in a variety of applications from measuring small electrical signals to significantly increasing or decreasing the power output of an electric motor. The PDB12-H4251-202BF is a type of rotary potentiometer or rheostat that offers exact control not only in terms of the resistance of the device, but also in terms of the voltage and power output.

Rotary potentiometers have two main components: a resistance element and a wiper. The resistance element (also known as a rotor or windings) consists of a conductor (typically a wire) wound around a core, forming a coil. The wiper is mounted on a shaft and rotates around the resistance element, sliding along it and making contact with the wire, thereby changing the resistance in the circuit. The PDB12-H4251-202BF is a linear type of rotary potentiometer, meaning it provides linear resistance (as opposed to a logarithmic type of rotary potentiometer). This makes it suitable for precise measurements and regulation of low-voltage electrical signals.

Unlike the common rotary potentiometer, the PDB12-H4251-202BF is a three-terminal device with an additional terminal. This terminal is connected to an internal resistor, which is adjusted by the wiper to adjust the voltage and power output of the device. This adds to the device’s flexibility since the user can adjust both the rate of voltage reduction (theshold level) as well as the speed of voltage increase (boost). The device is ideally suited for controlling the power of electrical motors, such as AC or DC motors that require precise voltage and current ratings.

The PDB12-H4251-202BF is also referred to as a rheostat. A rheostat (from the Greek words “rheo” meaning “flow” and “statos” meaning “state”) is essentially a variable resistor with two terminals. By adjusting the position of the wiper, the resistance in the circuit is changed, resulting in a change of the voltage or power output of the device. Rheostats are commonly used to control the speed of electric motors, such as in washing machines and electric drills. It is also used to adjust the brightness of lights, and can be found in audio amplifiers to control the volume.

The PDB12-H4251-202BF offers precise control of voltage and power output while providing linear resistance, making it suitable for a variety of electrical applications. This device is designed for use with AC or DC motors, and can be used for controlling the speed and power output of these motors. It can also be used in audio amplifiers and other devices that require precise adjustment of voltage or power output.
