AC Power Monitor Circuit
The AC Power Monitor is designed to provide real-time monitoring of AC voltage levels, ensuring that the power supply remains within specified operational parameters. It is equipped with sensors that continuously track the voltage levels on the AC power line.
In the event of an under-voltage condition, which may occur due to various factors such as load fluctuations or power supply issues, the monitor will register the voltage drop. If the voltage remains below the predefined threshold for a specified number of cycles, typically 5 or 6 consecutive cycles, the monitor activates an alert mechanism. This alert can be configured to trigger visual indicators, such as LED lights, or audible alarms, and can also be integrated with external systems for remote monitoring.
The schematic design of the AC Power Monitor includes several key components:
1. **Voltage Sensor**: This component measures the AC voltage levels and converts them into a readable format for processing. It typically utilizes a transformer or an opto-isolator for safe voltage measurement.
2. **Microcontroller**: The heart of the monitoring system, the microcontroller processes the voltage readings from the sensor. It is programmed with the logic to determine under-voltage conditions and counts the number of consecutive cycles that meet the criteria for triggering an alert.
3. **Alert System**: This can include both visual (LEDs) and audible (buzzers) indicators. The alert system activates upon detection of the predefined number of under-voltage conditions.
4. **Power Supply**: The monitor requires a stable power supply to operate. This can be derived from the AC line itself, often through a power supply circuit that steps down the voltage to a usable level for the monitor's internal components.
5. **User Interface**: Depending on the design, a user interface may be included to allow users to configure settings such as voltage thresholds and alert preferences.
Overall, the AC Power Monitor serves an essential role in ensuring the reliability and safety of electrical systems by providing timely alerts in the event of power anomalies, thereby enabling prompt corrective actions.This AC Power Monitor continuously watches the AC power line voltage for both under-voltage and missing cycles.
