CR4480-5 Current Transducers

The CR4480-5 is an advanced current transducer, manufactured by Celsa. This transducer uses a Rogowski coil – a non-contact device which produces a voltage signal proportional to the current flow – mounted in the CR4480-5 to monitor the current flowing through the input busbar. It is designed as a safety device, and can detect any current leakages or overloads with ease.

The CR4480-5 is a cost-effective solution for those looking to monitor current in a wide range of applications. This device is ideal for monitoring a vast array of different industrial applications including industrial automation, industrial motor control, energy management systems and electrical distribution systems.

One of the most important features of the CR4480-5 is its ability to accurately measure current up to 20 kHz, while offering a wide range of current measurement ranging from 0.1 A to 20kA. This corresponds to 0.1 mA to 2000 A for standard CR4480-5s. Furthermore, the CR4480-5 offers a 0.1% accuracy, with a ±1 A resolution.

Advantages

The CR4480-5 comes with a range of advantages for those looking to monitor and control current in a range of different applications. Firstly, the device is designed to offer very accurate current monitoring, with a wide-range of resolutions. This will enable users to accurately monitor current at high resolution. Secondly, due to its compact size, the CR4480-5 can be installed in even the smallest of locations. Lastly, the device comes with a temperature range of -20 to +80°C, which is perfect for a range of different industrial applications.

Working Principle

The CR4480-5 works by measuring the current through the input busbar through a Rogowski coil. The Rogowski coil is mounted inside the CR4480-5 unit, and produces a voltage signal proportional to the current flowing through the busbar. This voltage signal is then converted into current values and stored by the device. A range of safety features such as leakage current detection, overload detection and harmonic analysis are also available, allowing users to monitor and control the current reliably and safely.

Applications

The CR4480-5 is ideal for a variety of different applications in industrial and commercial sectors. Its ability to measure current up to 20 kHz means that it is well-suited for monitoring of high-speed industrial applications, such as motor control and energy management systems. In addition, its compact design means it can be installed easily in even the tightest of locations. This makes it perfect for applications where space is of a premium, such as data centers and substations. The CR4480-5 is also ideal for monitoring of residential and commercial electrical distribution systems, allowing users to monitor and control the current reliably and safely.

Conclusion

The CR4480-5 is a current transducer that provides accurate and high resolution measurement of current up to 20 kHz. Its compact design makes it ideal for a variety of different applications, such as motor control systems, energy management systems and electrical distribution systems. The device also offers a range of safety features, such as leakage current detection, overload detection and harmonic analysis, allowing reliable and safe monitoring of current.
