300A 75mV High power Current Alloy Shunt Resistors for AC or DC voltage measurement
100A to 600A
A current shunt, also known as a current sense resistor or current-sensing resistor, is a type of resistor specifically designed to measure or monitor the current flowing through a circuit. It is typically a low resistance value resistor connected in series with the load or the circuit being monitored.
The current shunt works based on Ohm's Law, which states that the voltage across a resistor is directly proportional to the current flowing through it. By measuring the voltage drop across the shunt resistor, the current flowing through the circuit can be determined using Ohm's Law (I = V/R).
Current shunts are commonly used in various applications such as power electronics, battery management systems, motor control, and industrial automation. They provide an accurate and reliable method of current measurement, allowing for monitoring and control of the current levels in a circuit.
