Manganin Plate Current-Shunt Resistor
As a typical precision alloy, manganin consists of 12% manganese, 4% nickel, and copper as balance. The most widely used models of manganin for shunts are 6J13 and 6J12. As its low thermal electromotive force (emf) and low TCR value, manganin shunt is widely used in energy meters, battery management systems, Wheatstone bridges and so on. We can also make C shape shunt resistors by brazing the pure manganin plate with copper lugs or brass blocks, which is more convenient for customers to install them.
For AC measurement, current transformers which provide safe galvanic separation, can replace manganin shunts, while the cost is higher. With more than 15 years experience, we can design many kinds of pure manganin shunts, as well as many other shunts of different structures and shapes.
