Maconic Shunt Resistors

Knick USA, an ISO 9001: 2008 certified global designer and manufacturer of analog signal conversion technologies, today introduced its Maconic Shunt Resistors, offering DC current measurements of up to kA range with industry best-in-class accuracy and reliability. Shunt resistors offer reliable, precise, cost-effective and continuous DC current measurements, in applications ranging from photovoltaics, to public transport system power supplies, to inverter DC busses, to welding equipment. The exceptional performance capabilities of these resistors allow them to be used in an even greater range of applications, including high-speed circuit breakers (HSCB); high-speed motors and generators; high-voltage battery monitoring; power transmission and switch gears; high-speed electric drives; and demanding DC current Bus measurements. Design of maconic shunt resistors reflects decades of field-proven engineering expertise. Each model is size and performance optimised for its intended task, with Class 0.5 and Class 0.2 accuracy. Their rod-based design allows for better heat dissipation, with improved thermal properties for increased overload conditions, all without affecting measurement integrity. Shunt resistor bars are constructed of high-conductivity manganin, allowing for a very low temperature coefficient and higher accuracy.
