Background

A shunt is a tool used to measure direct current, and according to ohm's law, in the same circuit, the current passing through a certain conductor is proportional to the voltage across the conductor and inversely proportional to the resistance of the conductor, i.e., I = U/R. When direct current passes through a resistor with a fixed resistance value, the voltage generated at two ends of the resistor is in positive correlation with the current. By the characteristic, on the premise of knowing the resistance of the shunt, the direct current of the circuit where the shunt is located can be measured by measuring the voltage at two ends of the shunt;

the common high-current shunt generally adopts metal or alloy as a current carrier, two ends of the shunt are provided with binding posts, the resistance value of the shunt is strictly controlled according to the specification, when the shunt is connected in series in a direct current circuit, direct current flowing through the shunt can generate voltage difference of millivolt level at the two ends of the shunt, and the current direct current can be calculated according to the voltage difference signal and the resistance value;

an embedded high voltage shunt with connector and solving the above problems are therefore proposed.
