The Analog Devices’s (ADI) AD650 is an electronic hybrid device specifically designed for the accurate measurement of ac voltage and current in the commercial power supply industry. It is a high-performance, low-cost, highly reliable device that can replace traditional transformer-based ac voltage and current transducers. The AD650 performs its task with minimal errors due to its wide frequency range, higher accuracy and low temperature coefficient. In this article, we will discuss the features and applications of the AD650 as well as its working principle.

Features and Applications of the AD650

The AD650 is an integrated electronic hybrid transducer that uses a direct-to-digital conversion technique to measure ac voltage and current. It is designed to be extremely precise and accurate over a wide frequency range and its high linearity and repeatability make it suitable for many applications in the commercial power supply industry. The AD650 has a wide operating temperature range of -40°C to 105°C and is capable of providing a precise and accurate output of 20mA at a frequency range of 45 to 66 Hz. The device is also highly reliable and has a long life expectancy of up to 10 years.

The AD650 is typically used as a replacement for traditional transformers-based transducers in the commercial power supply industry. It is designed for a wide range of applications such as power factor measurements, power line monitoring, voltage and current sustained load measurements, and load shedding. In addition, the AD650 is also suitable for use in AC motor speed and single-phase motor control systems.

Working Principle of the AD650

The working principle of the AD650 is based on a direct-to-digital conversion technique. This technique uses a digital signal processor (DSP) and an analog-to-digital converter to measure the voltage and current signals. The device first measures the ac voltage and current signals and converts them into an analog signal. Then the analog signal is converted into a digital signal using an a/d converter, which is then digitally filtered using the DSP. The processed signal is then displayed to the user.

The AD850 is designed with an adjustable gain feature, which allows the user to adjust the level of the analog signals in order to enhance the performance. The device also has a refresh function that enables the user to continuously monitor the voltage and current readings. The device also features an external reference input and calibration points, which can be used to improve accuracy.

Conclusion

The AD650 is a high-performance, low-cost and highly reliable device specifically designed for accurate measurement of ac voltage and current data in the commercial power supply industry. The device utilizes a direct-to-digital conversion technique to measure ac voltage and current signals and is suitable for applications such as power factor measurements, voltage and current sustained load measurements, and load shedding. Additionally, the device also features an adjustable gain, external reference input and calibrations point, as well as a refresh function.
