PDV15-21M-103A

Application Field:

The PDV15-21M-103A slide potentiometer is primarily used to control the speed or direction of an electrical motor. It can be used to adjust the voltage or current to a motor to achieve a desired speed or torque. It can also be used to regulate the flow of liquids and gases through a valve. Additionally, it can be used for lighting and other installation control purposes.

Working Principle:

The PDV15-21M-103A potentiometer works by adjusting the amount of voltage or current supplied to the motor or valve. This is accomplished by altering the resistance to the current or voltage, which then adjusts the performance of the motor or valve. The potentiometer is adjustable through an external control, which is usually a dial, knob, or switch.

When the potentiometer is adjusted to the correct setting, the current or voltage to the motor or valve is adjusted, thus controlling its speed or torque. This is done by the potentiometer changing the resistance to the current or voltage, which is then read by the motor or valve control circuit. The on-board resistors allow for precise adjustment of the resistance and therefore accurate control of the motor or valve performance.

Conclusion:

The PDV15-21M-103A slide potentiometer is a versatile and adjustable resistor that can be used to control motors, pumps, and valves. It can also be used for lighting and other installation control purposes. It works by altering the resistance to the current or voltage, allowing the user to adjust the speed or torque of the motor or valve.
