Farnell provides a broad selection of precision current shunts, offering low-resistance, high-accuracy variants tailored for demanding industrial and process-control environments. These components help measure high currents by converting them into proportional voltage drops, enabling safe and accurate monitoring.

Current shunts are critical in systems requiring reliable current sensing without bulky instrumentation. Installed in series with loads, they deliver precise measurements of electrical flow through precision resistance. With a wide range of resistance values, current ratings and mounting styles, they are highly versatile for various setups.

Applications:

Energy Management & Power Monitoring: Integrate with digital panel meters and data acquisition systems
Industrial Motor Control: Track current draw for overload protection
Battery Management Systems: Monitor charge/discharge currents in EVs and UPS setups
Automated Test Benches: Provide precise current measurements for calibration and diagnostics
