Product Overview
DC Current Transformer Series
Current or Voltage Output
Closed-loop current transformer technology allows accurate monitoring of DC and AC
bipolar currents up to ±100A.
Galvanic isolation between primary and secondary conductor for simple current
sensing at different potential.
Standard current output and voltage output (“V”-version) available.
The O-FLUCS (O-FLUx Current Sensor)
between the “C” option – a male DB-9
family is based on a closed loop
Connector – and the “P” option – 7-pin
• Monitoring of DC and AC currents
technology that allows accurate and
through-hole for PCB mounting.
• Excellent Linearity
precise monitoring of DC and AC
• Closed-loop detection
currents with high bandwidth.
• Galvanically isolated from primary
• Low Temperature Drift
The CT-100 transducers are rated at a
• Current-output or Voltage-output
at maximum bipolar primary current
• Wide Bandwidth
• High Accuracy
• UL 94 V-0 flammability grade
• LED indicates correct operation
• DB-9 Connector or PCB-mount versions
of 100A with a transformation ratio of
Galvanic isolation between the primary
and the secondary circuits allows to
measure currents at a different potential
and simplifies interfacing when using
the O-FLUCS as the feedback element

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.
All CT-100 devices also have different
mounting holes in order to be easily
