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

The metal casing guarantees higher noise immunity and reduces undesired noise pick-up from external sources.

The transducers CT-13, CT-26 and CT-52 are PCB-mount devices rated at maximum currents of 13A, 26A and 52A with primary to secondary transformation ratio of 1:250, 1:500 and 1:1000 respectively.

Galvanic isolation between the primary and the secondary circuits allows to measure currents at a different potential and simplifies interfacing if using the O-FLUCS as the feedback element of current regulated power supplies.

Output from the O-FLUCS sensors can be chosen between two different versions: standard secondary current output or buffered voltage output (low temperature coefficient shunt resistor and low-noise amplifier are embedded in the CT-13V, CT-26V and CT-52V versions).

Main characteristics of the O-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.

Due to the excellent characteristics, the O-FLUCS transformers can be used in a variety of calibration, acceptance testing and quality control applications in the industrial and automotive fields.

The compact mechanical dimensions of this transducer series and its limited weight allows easy mounting on printed circuit boards with a Through Hole (TH) topology.

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

Commercially available versions of the PCB-mount O-FLUCS current transformers are the current-output CT-13, CT-26 and CT-52 with their respective "V" voltage-output versions CT-13V, CT-26V and CT-52V.
