Description

High-Precision CT-400 Current Transducer

The CT-400 Current Transducer is engineered for accurate and reliable monitoring of DC and AC currents in critical applications. Utilizing the advanced 0-FLUCS (0-FLUx Current Sensor) closed loop fluxgate technology, it delivers unmatched linearity, negligible temperature drift, and extremely low noise performance. This makes it ideal for environments where precision and stability are crucial.

Rated for ±400 A bipolar primary current with a 1:2000 transformation ratio, the CT-400 converts high currents into precise secondary signals for accurate measurement and control. Galvanic isolation between the primary and secondary circuits ensures safe operation across different potential levels, simplifying integration into complex systems.

Flexible Output Configurations

The CT-400 Current Transducer comes in two versions: the current-output model provides a stable secondary current signal, while the buffered voltage-output version incorporates a low-noise amplifier and precision shunt resistor for direct voltage signal output. Both versions feature an LED operational indicator for easy verification.

Ideal Applications

This device is widely used in scenarios where precise and reliable current monitoring is essential:

  • EV battery testing and characterization
  • Calibration and laboratory setups
  • Industrial and automated test stands
  • AC mains monitoring for stable operation
  • Power inverters and regulated power supply systems

The CT-400 surpasses traditional Hall-effect sensors in linearity, low noise, and stability, making it a high-performance solution for automotive, industrial, and power generation applications. For optimal performance, it can be paired with the PS1215 low-noise AC/DC power supply or incorporated into the CT-BOX-400 system for a full bipolar current monitoring solution up to 400 A.
