Description
Hioki precision current clamps enable accurate, non-intrusive AC and DC current measurement without interrupting the circuit.
Precision current clamps are used where accuracy, ease of use, and minimal impact on the test setup are essential, including vehicle on-board measurements (incl. WLTP), power electronics testing, efficiency analysis, and measurements in hard-to-access environments.
Key Features
- Frequency bandwidth DC to 70 kHz, Rated current 2000 A DC, 1400 A AC
- Guaranteed combined accuracy when used with Hioki power analyzers
- Plug-and-play with Hioki Power Analyzer and Memory HiCorders
- Ideal for use in environmental testing with broad -40°C to 85°C temperature range
- Ideal for EV inverter evaluation and PV power generation PCS evaluation
- Single-handed operation and robust locking mechanism
Clamp-type sensors that eliminates the need to cut lines
Clamp-style current sensors can be affixed without cutting the line under measurement. Thanks to that design, they can measure current in applications where it’s not possible to cut lines, including testing of EVs on chassis dynamometers and evaluation of operational solar power systems.
Range reliability testing that complies with the WLTP international standard
The CT6840A series can measure current in operating vehicles since there’s no need to cut cables. Combined with a power analyzer, these instruments can accurately integrate current and power during charging and discharging of system batteries in order to make WLTP-compliant vehicle energy consumption measurement.
Realizing unparalleled measurement precision in a clamp-style design
While clamp-style current sensors are generally praised for their convenience, they usually pose disadvantages in terms of measurement precision. However, the CT6840A series delivers unparalleled measurement precision in a clamp-style design, allowing accurate measurement of DC power in battery-powered EVs and solar power systems.
Accurate current measurement across a broad operating temperature range of -40°C to 85°C
Temperature characteristics are an issue for current sensors that can manage DC current. The CT6840A series uses the flux gate detection method. Unlike the standard Hall element detection method, the flux gate method is more resistant to temperature variations, allowing instruments to accurately measure current in a variety of test environments.
Get reliable power results with the right setup—automatically
When paired with compatible power analyzers, phase-shift errors in the current sensor are automatically corrected.
Because HIOKI designs and manufactures both power analyzers and current sensors in-house, correction can be applied based on factory inspection data. This minimizes errors caused by sensor-to-sensor variation, even in dynamic measurements with high-frequency components, and improves confidence in power evaluation results.
It also helps engineers quickly achieve the correct setup, even without specialized knowledge of phase correction.
External Power Units (Compatible with Various Measurement Instruments)
These external power units supply power to current sensors and enable connection to a wide range of measurement instruments, including power analyzers, recorders, and oscilloscopes*.
Single-channel and four-channel models are available to support different measurement setups.
*Connect to instruments with an input impedance of 1 MΩ or higher.
