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 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-150 transducers are rated at a • Current-output or Voltage-output at maximum bipolar primary current 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 Applications • Power Supplies • Sensing Element in Calibration Systems • Biomedical Devices • Nuclear Magnetic Resonance (NMR) the O-FLUCS as the feedback element of current regulated power supplies. 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 can be chosen between two different installed in different configurations. Both versions: secondary current output or self-threading screws and normal ones buffered voltage output (low can be used. temperature coefficient shunt resistor and low-noise amplifier are embedded Main application fields for these current in the device). transducers are precise and extremely stable regulated power supplies and Also connection type can be chosen power inverters. Due to the excellent characteristics, the Commercially available versions of CT-150 transducers can be used The CT-150 current transformers are in a variety of calibration, acceptance the current-output CT-150-C and testing and quality control applications CT-150-P with their respective voltage- in industrial, power generation and output versions CT-150V-C and automotive fields.
