CT-150

Product Overview
CT-150
DC Current Transformer Series
Current or Voltage Output
Closed-loop current transformer technology allows accurate monitoring of DC and AC
bipolar currents up to ±150A.
Galvanic isolation between primary and secondary conductor for simple current
sensing at different potential.
Standard current output and voltage output (“V”-version) available.
Features
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 – 6-pin
• Monitoring of DC and AC currents
technology that allows accurate and

• Excellent Linearity
precise monitoring of DC and AC
• Closed-loop detection
currents with high bandwidth.
• Galvanically isolated from primary
• Low Temperature Drift
The CT-150 transducers are rated at a

versions
• Wide Bandwidth
• High Accuracy
• LED indicates correct operation
• DB-9 Connector or PCB-mount versions
of 150A 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

Output from the CT-150 transducers
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-150 devices also have different
mounting holes in order to be easily
