Metal Alloy Manganin Shunt
Based on the technology of bimetal alloy, we developed the manganin shunt resistors with resistance tolerance of 2% and temperature coefficient of 20ppm. Our high power electron beam welding machines and precision stamping machines make the EBW shunts possible. With more than 15 years experience, we can design and manufacture customized metal alloy manganin shunt of complicated structures, which can be used for cordless power tools, smart meters and so on.
