Description
CT6846A AC/DC Current Probe for Extreme High-Current Testing
The CT6846A AC/DC Current Probe from Hioki is engineered for high-current measurement applications where safety, precision, and efficiency are critical. As the highest-rated member of the CT6840A series, it supports currents up to 1000 A and is perfect for electric vehicle inverters, photovoltaic power systems, and large-scale battery testing.
Clamp Design for Large Conductors
The clamp-style design allows the CT6846A AC/DC Current Probe to be installed without cutting or disconnecting cables, improving safety and reducing setup time. Its large 50 mm clamp diameter accommodates high-current conductors used in EV traction systems and industrial energy setups. This design makes it easy to deploy in tight spaces, chassis dynamometers, and operational PV systems.
Accuracy with Flux Gate Detection
Unlike traditional Hall-effect sensors, the CT6846A AC/DC Current Probe uses flux gate detection, providing exceptional temperature stability and high-precision DC measurements. Engineers can rely on accurate readings even in environments with wide temperature fluctuations from -40°C to 85°C.
Integration with Hioki Instruments
This probe connects directly to Hioki Power Analyzers and Memory HiCorders, drawing power from the connected instrument. It supports automatic phase correction when used with the PW8001 Power Analyzer, eliminating manual configuration errors and ensuring precise power measurement. Optional units allow connection to oscilloscopes, DMMs, and power meters.
EV and Renewable Energy Applications
Engineers working on high-current EV systems, solar PCS evaluations, and environmental testing can depend on the CT6846A AC/DC Current Probe for reliable, safe, and accurate measurements. Its combination of clamp convenience, flux gate precision, and broad operating temperature range makes it an indispensable tool for modern energy applications.
