Current Sensing & Shunt Solutions
Precision Current Measurement Solutions for Industrial Demands
Ensure dependable current sensing and measurement across automotive, aerospace, energy, and telecom applications with our precision-engineered shunt assemblies.
A shunt and its assemblies are used to measure electrical current and represent one of the most widely adopted methods for current measurement. A shunt is a resistive element with a specific predefined resistance introduced into an electrical or electronic circuit. The voltage drop across this resistance is measured, and using Ohm's law, the corresponding current value is derived. This method enables instantaneous AC or DC current measurement.
Designed for accurate current sensing in batteries, inverters, power supplies, and energy meters.
Tight tolerance solutions for sensitive applications such as lab equipment and high-end electronics.
Engineered to your exact specs with special resistance ratings, thermal compensation, and mounting styles.
From high-voltage grounding to intricate signal protection, rely on our custom-woven assemblies for maximum conductivity and lifelong structural integrity.
