Description
CT6844A AC/DC Current Probe for Accurate High-Current Testing
The CT6844A AC/DC Current Probe is engineered for engineers and test professionals who require precise measurement of high AC and DC currents in real-world operating conditions. As part of Hioki’s CT6840A series, this probe combines the convenience of a clamp-type sensor with measurement accuracy typically associated with fixed or inline sensors.
Clamp Design for Non-Intrusive Measurement
The clamp-style structure of the CT6844A AC/DC Current Probe allows users to measure current without cutting or disconnecting conductors. This makes it especially valuable for applications where system interruption is not possible, such as EV testing on chassis dynamometers or evaluation of active photovoltaic power systems. Installation is fast, safe, and efficient, even in confined spaces.
High Accuracy Using Flux Gate Technology
Unlike conventional Hall-effect current sensors, the CT6844A AC/DC Current Probe uses the flux gate detection method. This approach significantly improves measurement stability and accuracy, particularly for DC current measurement. As a result, engineers can confidently capture precise current data in EV inverters, battery systems, and power conversion equipment.
Performance Across Wide Temperature Ranges
Environmental conditions often impact sensor accuracy. The CT6844A AC/DC Current Probe is designed to maintain reliable performance across a wide operating temperature range from -40°C to 85°C. This makes it suitable for environmental chambers, outdoor renewable energy installations, and automotive testing environments.
Integration with Hioki Power Analyzers
When connected to Hioki Power Analyzers such as the PW8001, the CT6844A AC/DC Current Probe supports automatic phase correction. This feature simplifies setup, reduces configuration errors, and ensures accurate power measurement by compensating for sensor phase characteristics. Power is supplied directly from the connected instrument, minimizing external wiring and improving system reliability.
EV and Renewable Energy Applications
Designed for modern power analysis needs, the CT6844A AC/DC Current Probe is ideal for EV inverter evaluation, battery charge and discharge analysis, and photovoltaic PCS testing. Its ability to measure high currents accurately, combined with ease of use and durability, makes it a dependable tool for advanced energy and mobility testing.
