Hioki CT6873 AC/DC Current Sensor

Overview

The Hioki CT6873 is a pass-through AC/DC current sensor with a frequency bandwidth of DC to 10MHz and a 200A rating. Designed for R&D, quality evaluation, manufacturing, and maintenance in wireless charging, inverter motors, and power conditioning for photovoltaic systems, it delivers the precision and stability required for state-of-the-art measurement. The sensor uses a zero flux method (fluxgate detection type) with hybrid detection of high-frequency currents via CT method and DC to low-frequency currents via fluxgate, ensuring robust noise resistance across a broadband of frequencies.

Key Features

• 200A current rating with DC to 10MHz bandwidth
• Highly accurate measurement across frequency spectrum
• Excellent frequency characteristics for broadband measurement up to 10MHz
• Hybrid zero flux method with fluxgate detection
• High common-mode rejection ratio (CMRR) for superior noise resistance
• Wide operating temperature range: −40°C to 85°C (suitable for automotive applications)
• Compatible with Hioki Power Analyzers, Memory HiCorders, and oscilloscopes (with sensor unit)
