Description
CT6841A AC/DC Current Probe for Accurate and Non-Intrusive Measurement
The CT6841A AC/DC Current Probe is engineered to meet the growing demand for precise current measurement in modern power electronics, electric vehicles, and renewable energy systems. Designed as part of Hioki’s high-performance CT6840A series, this clamp-type probe delivers laboratory-grade accuracy while preserving the convenience of non-contact measurement.
Clamp Design for Safe Installation
Unlike traditional current sensors that require cutting or disconnecting conductors, the CT6841A AC/DC Current Probe features a clamp-style design that allows safe and efficient installation on live systems. This makes it especially valuable for applications such as EV chassis dynamometer testing, operational solar power systems, and in-vehicle measurements where interrupting the circuit is impractical or unsafe.
High Bandwidth and Precision
With a frequency bandwidth extending from DC to 2 MHz, the CT6841A AC/DC Current Probe accurately captures fast-changing current waveforms, switching behavior, and transient events. Its use of the flux gate detection method ensures superior stability and accuracy compared to conventional Hall-effect sensors, particularly when measuring low-level DC currents.
Performance Across Temperature Extremes
Environmental conditions can significantly affect current measurement accuracy. The CT6841A AC/DC Current Probe is designed to operate reliably across a broad temperature range from -40°C to 85°C. This makes it well suited for environmental testing chambers, outdoor PV installations, and automotive testing environments where temperature variation is unavoidable.
Integration with Hioki Power Analyzers
When connected to compatible Hioki Power Analyzers, including the PW8001, the CT6841A AC/DC Current Probe supports automatic phase correction. This feature eliminates manual configuration errors and ensures accurate power measurement, saving setup time while improving confidence in test results. Power is supplied directly from the connected instrument, simplifying system configuration.
EV and Renewable Energy Applications
The CT6841A AC/DC Current Probe is ideal for EV inverter evaluation, battery charge and discharge analysis, and photovoltaic power generation testing. Its precision, durability, and ease of use make it a dependable solution for engineers, researchers, and test professionals working in advanced energy and mobility sectors.
