The device has a low-correction factor, which ensures accurate results.

The CR4820-150 also features multiple communication protocols, including RS485, USB, Ethernet, Modbus, and 4 to 20mA. This enables the device to be integrated into various types of systems and makes it easier to transmit data between the device and the computer. The device also features an auto-calibration mode that calibrates the device automatically to ensure optimal accuracy.

Working Principle

The CR4820-150 has a four-stage operation. First, the device uses transistors to detect the incoming electrical signal and convert it into an analog value measured in the microvolt range. This analog value is then converted to digital using an onboard converter and passed through various analog/digital filters. The filters are used to remove the noise from the signal and to normalize the signal. Finally, the filtered signal is converted to digital values in the microvolt range using a tenth-order low-pass filter.

Once the signal has been filtered and normalized, the device can measure voltage, current, power, frequency, and transducer and converter outputs. It uses analog/digital converters to measure the voltage, current, and power. The frequency is measured using a frequency counter and the transducer and converter outputs are measured using a multiplexer. The device is also capable of converting the analog value to a voltage or current output.

Applications

The CR4820-150 is designed for use in industrial applications for monitoring, control, safety, and protection of industrial systems, circuits, and equipment. It is commonly used to monitor electric parameters such as voltage, current, power, frequency, and transducer and converter outputs in factories, power plants, and other industrial facilities. The device can also be used in research and development, data acquisition, and data logging applications.

The CR4820-150 is also suitable for use in building automation, smart grid, voltage regulation, and protection systems. This device is extremely versatile and can be customized to suit any application. It is capable of measuring a wide range of parameters in multiple communication protocols, and the integrated display makes it easy to read the values in real time.

Conclusion

The CR4820-150 is a monitor-current/voltage transducer that is designed for use in industrial applications.
