Description
CT6875A AC/DC Current Sensor for Inverter Applications
The CT6875A AC/DC Current Sensor is a high-performance pass-through sensor engineered to meet the growing demands of modern power electronics. Designed for professionals working in research, manufacturing, quality evaluation, and maintenance, it delivers reliable and repeatable current measurements even in high-noise environments.
Zero Flux Technology
At the core of the CT6875A AC/DC Current Sensor is Hioki’s advanced zero flux method, which combines flux gate detection for DC and low-frequency currents with CT detection for high-frequency signals. This hybrid approach ensures excellent linearity, low offset, and stable accuracy across a wide range of current levels. The result is highly dependable data for critical measurements such as inverter efficiency, transformer loss, and long-term DC monitoring.
Wide Frequency Band
With a frequency bandwidth of DC to 2 MHz for amplitude and DC to 1 MHz for phase, the CT6875A AC/DC Current Sensor captures fast-switching waveforms with clarity. This makes it well suited for evaluating high-speed inverters, wireless charging systems, and EV power electronics where signal precision is essential.
High Noise Resistance
Accurate measurement in electrically noisy environments is achieved through a reinforced shielding design. The enhanced noise resistance allows the CT6875A AC/DC Current Sensor to detect current signals buried in noise, ensuring trustworthy results during real-world testing conditions.
Smart Connectivity
When paired with Hioki Power Analyzers such as the PW8001, the sensor automatically transfers phase correction data, rated current, model information, and serial number via its built-in memory. This automation reduces setup time, eliminates manual input errors, and improves overall measurement accuracy.
Future-Ready Power Systems
Built to support next-generation energy systems, the CT6875A AC/DC Current Sensor is ideal for photovoltaics, fuel cells, EV fast charging, and industrial inverter motors. Its durability, accuracy, and wide operating temperature range make it a dependable choice for both laboratory and field use.
