Description
CT6845A AC/DC Current Probe for High-Current Power Analysis
The CT6845A AC/DC Current Probe is engineered for professionals who require accurate and reliable measurement of high current levels in modern power systems. As part of Hioki’s advanced CT6840A series, this probe combines clamp-type convenience with precision measurement performance, making it a trusted solution for EV, renewable energy, and industrial power testing.
Clamp Design for Large Conductors
The clamp-style construction of the CT6845A AC/DC Current Probe allows engineers to measure current without disconnecting or modifying wiring. Its large clamp diameter supports conductors up to 50 mm, making it well suited for high-current applications such as EV traction systems, battery packs, and solar power conditioners. This design improves safety, reduces downtime, and simplifies test setup in both laboratory and field environments.
Accuracy with Flux Gate Detection
To deliver consistent and precise DC measurements, the CT6845A AC/DC Current Probe uses flux gate detection technology. This method provides superior temperature stability compared to conventional Hall-effect sensors. As a result, current readings remain accurate even during extended tests or when operating in environments with fluctuating temperatures.
Performance in Environmental Testing
Environmental and durability testing often requires instruments to function across extreme temperature ranges. The CT6845A AC/DC Current Probe is rated for operation from -40°C to 85°C, ensuring dependable performance in climatic chambers, outdoor installations, and automotive testing facilities. This wide operating range supports accurate data collection under real-world conditions.
Integration with Hioki Instruments
The CT6845A AC/DC Current Probe connects directly to Hioki Power Analyzers and Memory HiCorders, drawing power from the connected instrument. When paired with the PW8001 Power Analyzer, automatic phase correction is supported, helping eliminate configuration errors and improving the accuracy of power calculations. The probe can also be used with oscilloscopes, power meters, and digital multimeters when an optional sensor unit is added.
EV and Renewable Energy Applications
Designed for demanding applications, the CT6845A AC/DC Current Probe is ideal for EV inverter evaluation, battery charge and discharge testing, and photovoltaic PCS analysis. Its ability to measure high currents safely and accurately makes it a valuable tool for engineers working on next-generation energy systems.
