Energy Meter Manganin Shunt
Due to high linearity and good temperature stability, our manganin shunts are widely used for energy meters and other instruments of measurement. We can provide precision shunt resistors with temperature coefficent as low as 20ppm, and resistance tolerance less than 2%. We can also provide mini current transformers for energy meters, which have the advantage of good galvanic separation.
