Overview
Accurate and precise monitoring of DC and AC currents with high bandwidth, low noise and negligible drift.
The 0-FLUCS (0-FLUx Current Sensor) current transducer family is based on a closed loop technology that allows reaching best-in-class performance for a variety of applications.
The CT-2000 transducers are rated at a at maximum bipolar primary current of 2000 A with a transform ratio of 1:2000.
Galvanic isolation between the primary and the secondary circuits allows to measure currents at a different potential and simplifies interfacing when using the 0-FLUCS as the feedback element of current regulated power supplies.
Output from the CT-2000 transducers can be chosen between two different versions: secondary current output or buffered voltage output (low temperature coefficient shunt resistor and low-noise amplifier are embedded in the device).
Main characteristics of the 0-FLUCS current transformers are negligible temperature coefficient on the secondary output current, excellent linearity and extremely low noise.
DC current transformers represents the ideal replacement for systems where Hall-effect sensors are used as current sensing elements and better performances are needed.
0-FLUCS exclusive technology allows the user to obtain performances which cannot be reached with other current sensing techniques.

0-FLUCS Exclusive Technology – An Overview
Ideal for EV, battery testing, current calibration, AC mains monitoring and precision power supplies.
Main application fields for these current transducers are all the ones where the accuracy and precision of the current measurement is critical:
- battery testing and characterization (EV);
- calibration setups;
- test stands;
- precise AC mains monitoring;
- extremely stable regulated power supplies;
- power inverters.
Due to the excellent characteristics, the CT-2000 transducers can be used in a variety of calibration, acceptance testing and quality control applications in industrial, power generation and automotive fields.
Commercially available versions of the CT-2000 current transformers are the current-output CT-2000 and the respective voltage-output version CT-2000V. A LED indicating the correct operation of the device is present on all versions.
The dedicated power supplies for the CT-2000 and CT-3000 current transducers are also available for both the current output (PS1124I) and voltage output (PS1124V) versions.
