LIBRA ENERGY AUTOMATION PANEL
Libra is an advanced Plug & Play solution for monitoring and managing Low- and Medium-Voltage electrical loads, Power Quality analysis, DC measurement of renewable energy generation, and the monitoring of environmental, process, and indoor air quality parameters.
The system is custom-configured to meet the specific requirements of each installation and can support up to 7 three-phase measurement points or up to 21 single-phase measurement points, enabling fast, simple, and non-invasive installation on existing electrical systems.
Libra can be seamlessly integrated into an existing Electrex energy monitoring network, used as the central controller, or serve as the foundation of more advanced supervision systems thanks to its ability to connect additional Electrex devices via RS485 subnetworks and/or Ethernet.
The integrated energy analyzer provides Class 0.5S accuracy for Active Energy measurement. It measures individual harmonics up to the 51st order and performs comprehensive Power Quality analysis according to EN 50160 (voltage sags, swells, interruptions, and harmonics) and EN 61000-4-30 Class S, including graphical event visualization, event tables, event timelines, configurable measurement campaigns, selectable parameters, and programmable sampling intervals.
The Libra UPS version includes an integrated battery backup to ensure continuous operation of the measurement system. It is particularly recommended for applications requiring automated control functions and alarm management, while also guaranteeing uninterrupted monitoring and recording of Power Quality events.
Libra features an integrated astronomical real-time clock/calendar and non-volatile memory for the synchronized recording of both energy and environmental data.
The integrated Web Server enables remote supervision of the installation, providing access to real-time measurements and historical trend graphs through any standard web browser.
Depending on the application, Libra can also be equipped with inputs for Electrex environmental sensors (such as temperature, humidity, luminosity, pressure, CO₂, particulate matter, VOC, etc.), as well as digital inputs/outputs (status or pulse counting) and analog inputs/outputs.
