Low loss current shunt type Excs02
Measuring current is often done by measuring a voltage across a current sensing resistor, a so called shunt resistor. The value of this resistor is chosen as low as possible and in practice a voltage drop of 100mV is common. Sometimes this voltage drop is unacceptable but lowering the value of the shunt resistor is not always possible because of the low voltage.
The Excs02 uses a different approach by measuring the magnetic field around a conductor. With a maximum current of 30 Amps and a resistance of less than a milli ohm the Ext-Ins current shunt is suited for demanding measurements with low voltage loss.
