Riedon Model SSD-500A Series Shunt Sensor – Digital by Bourns with 500A nominal current. The extended electrical rating allows designers to utilise a supply voltage of 24V (15mA typical), allowing ...
Current shunt resistors are low resistance, passive electronic devices used to measure alternating current (AC) or direct current (DC) by the voltage drop those currents create across the resistance.
There’s many different ways of measuring current. If it’s DC, the easiest way is to use a shunt resistor and measure the voltage across it, and for AC you could use a current transformer.
