Current transducers, or current sensors, are electronic components used to detect, control, and monitor electric currents in a system. The CQ3200 is a type of current transducer that measures AC or DC currents in order to provide dynamic power measurements with high accuracy and reliability.

Applications

The CQ3200 is widely used in a variety of applications including Uninterruptible Power Supplies (UPS), motor drives, inverter-driven systems, and energy metering. It can be used to precisely monitor motor currents in motor drives, power conversion systems, and UPS systems as well as providing high precision current measurement and sensing in a range of other industrial and power electronics applications. It is also regularly used in electric vehicle chargers and other renewable energy initiatives.

The CQ3200 current transducer is also widely used in medical applications such as medical imaging systems, ultrasound scanning systems, and CT scans. It can be used to provide accurate current measurement for patient safety and device protection. The CQ3200 is also ideal for research and development involving current measurement, control and power monitoring applications.

Features

The CQ3200 is designed with a reliable, low temperature coefficient, and a high accuracy current range of up to 80A. It features an improved connection range of up to 125A and an accuracy of 0.1%. The CQ3200 provides overload current protection, reverse connection protection, and open-loop protection features. It also features a wide temperature range and is designed to operate up to +85°C in order to maintain high performance over a wide range of conditions.

The device features a built-in isolation transformer and a three-coil structure for improved accuracy. It also has a low insertion loss of less than 1% and is designed to operate in a wide range of operating frequencies. With low power consumption, low harmonics, and a low torque, the CQ3200 is ideal for a range of applications.

Working Principle

The CQ3200 current transducer is designed with a closed loop operation, which means it works by measuring the induced voltage between two closed loops of wire. The voltage induced between the two wires is proportional to the current flowing through them and is used as a reference signal for the transducer to measure.

The CQ3200 uses its three-coil structure to measure current. The first coil, called the primary coil, is wound around an iron core and is used to induce the current. The second coil, or secondary coil, surrounds this iron core and is connected to an additional electrical circuit. When a current is introduced in the primary coil, the secondary coil creates a proportional current in this additional circuit.

This produces a voltage in the secondary coil that is proportional to the current in the primary coil. This signal is then amplified and used to measure the current flowing through the primary coil. The transducer then generates a signal proportional to the measured current, which is used for control and monitoring of the system.

Conclusion

The CQ3200 is a type of current transducer designed for use in a variety of industrial and medical applications. It provides high accuracy current measurements and monitoring with overload, reverse connection, and open-loop protection features. The device works by using a three-coil structure to induce a current in the primary coil, which creates an induced voltage in the secondary coil that is proportional to the current in the primary coil. This signal is then amplified and used to measure the current flowing through the primary coil.
