Accuenergy DC Current Shunt

Accuenergy DC current shunt is engineered for precision measurement in DC current systems. Shunts are designed to measure electrical currents based on a small voltage drop created across a high-precision resistor placed in series with a load. When connected to a DC power meter, DC current shunts provide accurate energy measurements in a variety of applications including renewable energy, mass transit, battery charging, electric vehicles, welding, heavy industrial environments, and OEM applications.
