Maconic Shunt Resistors

Interface Technology ProLine

Maconic shunt resistors are the result of many years of experience in the design and production of such resistors. They are carefully manufactured using high-quality materials. The resistor bars are made of manganin, a special manganese-copper-nickel alloy, so that a very low temperature coefficient is achieved. Dimensioning and mechanical construction are selected so that the resistors only heat up slightly up to the rated current.

The shunt resistors and associated shunt isolators achieve very good long-term stability, which guarantees the specified accuracy over the normal periods of application of many years. Current peaks do not cause any offset or drift. Protection equipment based on current measurement benefits from the reliability and long-term stability of the measurement and achieves a particularly high level of safety performance.
