The 0-FLUCS (0-FLUx Current Sensor) family is based on a closed loop technology that allows accurate and precise monitoring of DC and AC currents with high bandwidth, very low noise and negligible drift.

The CT-100 transducers are rated at a at maximum bipolar primary current of 100A with a transformation ratio of 1:1000.

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-100 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).

Also connection type can be chosen between the 'C' option – a male D-sub 9 Connector, also know as DE-9 or DB-9 – and the 'P' option – 7-pin through-hole for PCB mounting.

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.

All CT-100 devices also have different mounting holes in order to be easily installed in different configurations. Both self-threading screws and normal ones can be used.

Main application fields for these current transducers are precise and extremely stable regulated power supplies and power inverters.

Due to the excellent characteristics, the CT-100 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-150 current transformers are the current-output CT-100-C and CT-100-P with their respective voltage- output versions CT-100V-C and CT-100V-P. An LED indicating the correct operation of the device is present on all versions.
