Description
CT6843A AC/DC Current Probe for Professional Power Testing
The CT6843A AC/DC Current Probe is designed to meet the demands of modern electrical and power electronics testing. As part of Hioki’s CT6840A series, this probe delivers exceptional measurement accuracy while maintaining the convenience of a clamp-type sensor. It is well suited for engineers working in automotive, renewable energy, and industrial power analysis applications.
CT6843A AC/DC Current Probe Clamp Design for Safe Installation
The clamp-style structure of the CT6843A AC/DC Current Probe enables current measurement without disconnecting or cutting cables. This non-intrusive approach improves safety and reduces setup time, making it ideal for testing live systems. The compact clamp head allows easy installation in confined spaces with complex wiring, including EV powertrains and solar inverters.
Accuracy Using Flux Gate Technology
To ensure stable and precise DC current measurement, the CT6843A AC/DC Current Probe uses flux gate detection technology. Compared to traditional Hall-effect sensors, this method offers superior resistance to temperature-related drift. As a result, users can rely on accurate data even during long-duration tests or when ambient temperatures fluctuate.
Performance in Harsh Environments
Environmental testing often exposes instruments to extreme temperatures. The CT6843A AC/DC Current Probe is rated for operation from -40°C to 85°C, ensuring dependable performance in climatic chambers, outdoor renewable installations, and automotive testing environments. This wide temperature tolerance supports consistent results across a broad range of conditions.
Compatibility with Hioki Instruments
The CT6843A AC/DC Current Probe connects directly to Hioki Power Analyzers and Memory HiCorders, receiving power from the measurement instrument. When used with the PW8001 Power Analyzer, automatic phase correction is supported, simplifying setup and ensuring accurate power calculations by compensating for sensor phase characteristics.
EV and Renewable Energy Applications
This probe is particularly well suited for EV inverter evaluation, battery charge and discharge analysis, and photovoltaic PCS testing. Its combination of high bandwidth, stable DC measurement, and clamp-type convenience makes the CT6843A AC/DC Current Probe a reliable solution for precise current monitoring in advanced energy systems.
