Avr Card

Product Details:

An AVR (Automatic Voltage Regulator) card for a generator is a critical component of a generator control system that helps maintain a stable and consistent voltage output from the generator. It is designed to regulate the generator's output voltage, ensuring that it remains within acceptable limits, even when there are variations in load or other external factors. Here's a description of the AVR card and its key features:

Components and Features of a Generator AVR Card:

1. Microcontroller/Processor: The AVR card is typically equipped with a microcontroller or processor that monitors and controls the generator's voltage output. It processes data from various sensors and makes adjustments as necessary.

2. Voltage Sensors: Voltage sensors are used to measure the output voltage of the generator. These sensors provide real-time data to the AVR card, allowing it to detect voltage fluctuations.

3. Reference Voltage: The AVR card is programmed with a reference voltage value, which represents the desired output voltage level. The card compares this reference voltage with the measured voltage and makes adjustments to minimize any deviation.

4. Adjustment Mechanism: To regulate the generator's output voltage, the AVR card can adjust the field current supplied to the generator's exciter. By controlling the excitation level, the generator's voltage can be increased or decreased as needed.

5. Stability Control: AVR cards often include stability control features to prevent sudden voltage spikes or drops. This ensures that the generator output remains stable under varying load conditions.

6. Overvoltage and Undervoltage Protection: The AVR card may incorporate protective measures to prevent the generator from producing excessively high or low voltages, which could damage connected equipment. It can issue shutdown commands or trigger alarms if voltage levels go beyond safe limits.

7. Communication Interfaces: Many modern AVR cards have communication interfaces (e.g., RS-485, Modbus) to connect with other monitoring and control systems, allowing for remote monitoring and data logging.

8. User Interface: Some AVR cards have a user-friendly interface for configuring settings and monitoring the AVR's performance. This can include an LCD display and keypad for manual adjustments and status monitoring.
