About the three-phase automation module

Four-quadrant measurements for energy efficiency

This device is capable of measuring both capacitive and inductive loads, allowing for precise control of imported and exported active energies. With this functionality, it is possible to obtain a comprehensive view of energy consumption, helping to optimize efficiency and reduce operational costs. Four-quadrant measurement is especially useful in industrial environments, where load variation can be significant, ensuring that you always have reliable and accurate data on the energy performance of your facilities.

Class B accuracy for active energy

With an accuracy of 1%, the device ensures that active energy measurements are extremely reliable. This accuracy is crucial for industrial and commercial applications, where precise monitoring of energy consumption can directly influence operational costs. Class B accuracy guarantees that the data obtained is consistent and helps make informed decisions about energy management, contributing to a more sustainable and efficient environment.

Advanced connectivity with MODBUS support

Connectivity is one of the major advantages of this equipment, which supports not only Wi-Fi and LAN but also Bluetooth. The ability to integrate with existing systems through the MODBUS protocol facilitates implementation in already established industrial installations. Additionally, compatibility with MQTT and WebSocket allows for efficient real-time communication, making energy management more accessible and intuitive, regardless of network complexity.

Real-time energy monitoring

The ability to monitor single-phase electrical systems with up to three points simultaneously is one of the most impressive features. With quick notifications and data storage for up to 60 days at one-minute intervals, it is possible to track energy performance in real time. This functionality is essential to avoid unpleasant surprises, such as consumption spikes or voltage drops, which can damage equipment and increase costs. The visualization of power quality allows for proactive and informed management.

High-level industrial security

Security is a priority, and this device does not disappoint. With support for mTLS in MQTT, HTTP, and secure WebSockets, it ensures that communications are protected against unauthorized access. This feature is vital for companies that need to integrate cloud solutions without compromising data security. The robustness of industrial security allows for a simpler and more efficient implementation, eliminating the need for complex networks and VPNs, thus reducing costs and increasing operational efficiency.

Bidirectional consumption monitoring

The ability to monitor energy consumption bidirectionally is one of the most valuable features. This equipment allows for the calculation of energy produced and used in each of the three phases, providing a detailed view of energy performance. With this information, it is possible to avoid unnecessary expenses and voltage drops, protecting connected devices and optimizing energy use. The visualization of parameters such as active power, reactive power, voltage, and power factor provides an in-depth understanding of the energy efficiency of the installation.
