Slide Potentiometers

Slide Potentiometers refer to a type of adjustable resistor device which can be used to measure electrical potential or the power of signals. The PDV15-21P-103A Slide Potentiometer offers a choice of two different rotation angles, 15 degrees or 21 degrees, and is rated up to 103A.

Application Fields

The PDV15-21P-103A Slide Potentiometer is mainly used in industrial and commercial applications, as well as medical equipment. Its wide temperature range allows it to function properly in harsh environments and in extreme heat or cold.

Its most common applications include motor speed control, inverter frequency control, scene lighting, electric door locks, LED dimming control, automatic voltage regulators, AV power supply controls, switchboards and signal amplifiers, etc. It can also be used to measure the energy input of generators, and detect the signals sent from different medical devices such as imaging/ultrasound systems and rehabilitation machines.

Working Principle

The PDV15-21P-103A Slide Potentiometer works by relying on the principle of resistive potential difference. Its three main terminals–A for the single end, B for the center connection, and C for the other single end–are designed to adjust the potential within a controlled range. When the terminals A and C are set at the same potential, the B terminal remains at a constant voltage. When the terminals A and C are not at the same potential, then the B terminal will be at a variable voltage.

The unit then measures the change of resistance by moving the slider along the resistive material in order to adjust the potential difference between the terminals. As the slider movement causes a variation in voltage, the measured voltage can then be used to determine the power of the signal. By adjusting the resistance value, the PDV15-21P-103A Slide Potentiometer can also be used to dampen vibration signals.

Due to its compact size and straightforward design it is one of the most widely-used pieces of equipment in many practical electronic circuits. The adjustable range of the PDV15-21P-103A makes it ideal for controlling small motors, and for providing precise voltage and current measurements in audio and video signal processing.

Conclusion

The PDV15-21P-103A Slide Potentiometer is a versatile and reliable tool for measuring electric potential or the power of signals. Its adjustable range and temperature resistance make it suitable for various industrial, commercial and medical applications. It is also a user-friendly and affordable piece of electronics equipment which provides precise and reliable voltage readings.
