The RCL200E is a type of rotary potentiometers, rheostats,and more specifically, it is a specialty electronic controlled variable resistor. It is specifically designed to be used in applications such as voltage and current regulation, control applications, and many other such applications. It is a popular choice because of its long life expectancy, reliability, low cost, and ease of use.

The RCL200E is constructed with a traditional multi-turn potentiometer design, with a plastic housing that encloses the terminals. It features an integral spring loaded locking nut that prevents accidental turning or adjustment. Its design also limits the torque needed for adjustment to ensure its durability, helping it to withstand even the toughest environments such as those found in industrial applications.

At its core, the RCL200E consists of three pins—the center tap pin, the body pin, and the end pin. The center tap pin can be used to determine the potentiometer’s resistance, while the body pin and the end pin serve as connectors for the external circuit elements. By changing the connection between the pins, users can adjust the electrical parameters.

The RCL200E features three operating options: homothetic, helical, and linear. Homothetic operation is the default setting. It is well-suited for applications where a continuous adjustment over low to mid resistance ranges is desired. The helical option is better suited for mid to high resistance ranges, as the helical design reduces the number of turns needed for a given voltage or current adjustment. The linear option is most suitable for applications where precise adjustment over large resistance ranges is needed.

The RCL200E utilizes a bandgap reference technology, which allows precise control over its current and voltage range. This is achieved through voltage or current regulation, where the RCL200E continuously monitors and adjusts its voltage or current output to match the desired value. In addition, its built-in filtering capabilities work to reduce ripple and other noise in the controlled medium.

The RCL200E is highly efficient, boasting a power dissipation of only 7mW at 5 volts. Its on-resistance also remains low over a wide range of temperatures—from -20C up to 85C. This allows it to maintain consistent performance in even the toughest of conditions.

The RCL200E is a versatile and reliable device that is well-suited for a wide range of application fields. Some examples include, but are not limited to, LED lighting, telecommunications, computer peripherals, instrumentation, and HVAC, among many others. Its combination of speed, accuracy, and reliability make it an excellent choice for any application.
