Working Principle of 90PR500LF

The 90PR500LF is a trimmer potentiometer which consists of a resistive element, a protective barrier film and a movable actuator. The primary purpose of the device is to regulate the voltage or current in a circuit. Its working principle can be summarised as follows: When an input voltage (Vin) is applied across the device, the voltage across the resistor will be proportional to the position of the actuator. As the actuator is adjusted, the voltage across the resistor will vary accordingly. The output voltage (Vout) can then be taken from the terminals of the resistor. The output voltage is related to the input voltage by the following equation:

Vout = ( Vin - Vmin ) X ( Actuator Position / 100 ) + Vmin

Vin is the input voltage, Vmin is the minimal operation voltage and the Actuator Position is the current position of the actuator. By adjusting the voltage according to the equation above, the 90PR500LF can be used to adjusting the voltage in a circuit.

Conclusion

The 90PR500LF is a trimmer potentiometer that is specifically designed for precision power applications. It is a versatile device that can be used in a wide range of applications such as adjustable voltage regulators, adjustable current sources and precision power supply circuits. Its working principle is based on the adjustment of the voltage across the resistor, relative to the position of the actuator. With its adjustable voltage and current capabilities, the 90PR500LF is a reliable and cost-effective solution for power applications.
