Description
AC/DC CURRENT SENSOR CT6873. Low-current Model of 200 A Rating, with Wideband and High Accuracy.
Overview
Hioki’s pass-through type AC/DC current sensors can be connected directly to Hioki Power Analyzers and Memory HiCorders. Also, it can be connected to Power Meters, Oscilloscopes, DMMs, etc. by using an optional sensor unit.
The CT6873 has a frequency bandwidth of DC to 10 MHz and a rated current of 200 A. It is used for R&D, quality evaluation, manufacturing, and maintenance in markets such as wireless charging systems, inverter motors for industrial equipment, power conditioners for PV, and quick charging facilities for EVs.
Key Features
-
Rated current: 200 A AC/DC.
-
Frequency bandwidth: Amplitude from DC to 10 MHz.
-
Phase bandwidth: DC to ~1 MHz.
-
High accuracy: For example, amplitude accuracy at DC: ±0.03 % reading ±0.002 % full scale. At 45–66 Hz: ±0.03 % reading ±0.007 % full scale, phase ±0.05°.
-
Output voltage ratio: 10 mV/A (rated) when used with the proper sensor unit.
-
Safety: Max rated voltage to earth: 1000 V, CAT III.
-
Aperture/core diameter: φ 24 mm (0.94 in) for conductor passed through.
-
Wide operating temperature: –40 °C to +85 °C (80% RH or less, no condensation).
-
Technology: Uses a combination of flux-gate (for DC/low-freq) + CT winding (for high-freq) for excellent linearity, low offset, wide bandwidth.
-
Compatibility: Can be connected (via optional sensor units) to oscilloscopes, memory recorders, power analyzers. Spec sheet indicates automatic phase‐correction when used with compatible instrument.
