Product Overview DC Current Transformer Series CT-PCB Current or Voltage Output Closed-loop current transformer technology allows accurate monitoring of DC and AC bipolar currents up to ±52A with a small PCB-mount device. 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) and low-noise amplifier are embedded family is based on a closed loop in the CT-13V, CT-26V and CT-52V). • 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.
