Working Principle of D175K5R0

The D175K5R0 adjustable power resistor is designed to absorb the excessive current or energy generated during operation. The resistor works by allowing a predetermined and predefined amount of current to pass through its resistance element.

The resistor is designed to limit the current to the required level. The resistor consists of a resistor element, a rod or a winding element, with two screws as ends which can be adjusted to set the desired current limit. These screws are linked to the external terminals, and by adjusting them one can achieve a desired current limit.

When the load current draws excessively, the adjustable power resistor conducts the excess current through its resistor element and limits the current to the desired level. This helps to protect the electronic components from the excessive power surge and provides a safe and reliable operation of the connected electronic equipment.
