A current transducer is an electrical device which is used to measure current, power and voltage. The CR4420-75 transducer is a state-of-the-art device with a range of 0 to 75 amps AC or DC. This device is designed for applications including industrial process monitoring, motor control, power measurements, motor protection and AC / DC measurement, among others.

The CR4420-75 is a Hall Effect Current Transducer that uses the Hall Effect, which was discovered in 1879 by Edwin Hall, to measure current through a conductor. Hall Effect transducers sense the magnetic field created by a current in a wired loop and convert it to a proportional voltage. The CR4420-75 utilizes an open loop design for improved accuracy and reliability. This device also features a mathematical integration algorithm which eliminates zero-cross errors and a response time of less than one millisecond.

The CR4420-75 is ideal for a variety of power monitoring and control applications due to its small size and high accuracy. The device has a compact, modular design that is easily integrated into existing systems. Additionally, the transducer features a wide operating temperature range of -25°C to 85°C. This allows it to be used in harsh and extreme environments.

The CR4420-75 is a three-wire device, with two of the wires being used to supply power and the third wire being an analog output. The output voltage is proportional to the sensed current in its engineering unit of mA or V. The device can be connected to a signal conditioner and/or an amplifier to provide an amplified output, as well as digital connectivity to an SCADA system. The CR4420-75 also has some overload protection features built in, ensuring that it does not become damaged if the current exceeds the maximum range.

The CR4420-75 is also designed for easy calibration and setup. The integrated Calibration/Setup Wizard guides you through the installation process, providing step-by-step instructions for calibrating the device and/or setting up the desired parameters. Additionally, the device is designed with standard set screws, allowing the configuration and readjustment of its outputs.

The CR4420-75 is a powerful, reliable and accurate current transducer that is ideal for a variety of industrial and electrical applications. With its wide application field and easy-to-use features, the device is extremely user-friendly and can be easily integrated into existing systems.
