Introduction:
The AD737KRZ-R7 is a monolithic, precision peak current-mode RMS to DC converter. By converting RMS AC signals to DC current, this device provides a means to monitor AC/DC power in an appliance, lighting fixture, or industrial process. It is also useful for controlling DC power in uninterruptible power supplies (UPS). The AD737KRZ-R7 provides the user a wide range of features and options that make it suitable for various applications, including industrial, system automation, appliance, retail, and many more.AD737KRZ-R7 Application Field
The AD737KRZ-R7 can be used in a variety of applications. It is ideal for detecting when an AC power source is active or detecting when a DC voltage is above or below a threshold voltage. Additionally, it can be used for AC/DC power measurement, power factor correction, and for driving a load or controlling lights. It can also be used for digital automation and industrial process control.AD737KRZ-R7 Working Principle
The AD737KRZ-R7 is a peak current-mode RMS to DC converter. It measures the root mean square (RMS) voltage of an AC voltage and then converts it to a steady DC current. The device also has reference comparators that can be used to set thresholds, as well as digital inputs and outputs for remote control and monitoring. The device consists of a voltage-controlled oscillator, a voltage-to-current converter, and a peak detector. The oscillator generates a periodic current which is proportional to the input voltage, and the voltage-to-current converter transforms that current to a linear voltage. The peak detector then stores the peak voltage value, which is then converted back to a current. This current is the RMS current and is proportional to the input voltage. The AD737KRZ-R7 also has reference comparators which can be used to set thresholds. By setting the reference voltage, the comparators can detect when the input voltage crosses the reference voltage, for example when an AC power source is active or when a DC voltage is above or below a set threshold.Conclusion
The AD737KRZ-R7 is a precision peak current-mode RMS to DC converter, making it ideal for applications that require monitoring AC/DC power, detecting when an AC power source is active or when a DC voltage is above or below a threshold voltage, measuring AC/DC power, power factor correction, and digital automation and industrial process control. Its wide range of features and options make it suitable for a variety of applications.The specific data is subject to PDF, and the above content is for reference
