Three-Phase Network Analyser Panel Circutor CVM-C11-ITF-IN-485-ICT2

The CVM-C11-ITF-IN-485-ICT2 Circutor three-phase network analyzer is a high-performance device designed for monitoring and analyzing electrical variables in Medium and Low Voltage systems. With a compact panel format (96 x 96 mm), this device is ideal for supervising electrical parameters such as voltages, currents, active and reactive powers, harmonics, and supply quality. Its ability to measure in four quadrants (consumption and generation) makes it highly versatile, allowing both energy consumption control and monitoring of generated energy.

Main Features:

This analyzer can measure and record the Total Harmonic Distortion (THD%) in voltage and current, as well as individual harmonics for each phase up to the 31st harmonic, providing a detailed view of the energy quality in the installation. Additionally, the CVM-C11 includes the ability to measure the neutral current, which is essential for detecting system imbalances and potential neutral conductor overloads.

The panel design facilitates its integration into any electrical installation, and its graphical interface with a backlit LCD screen provides a clear data display, allowing the user to configure the parameter display according to their needs. Among the advanced display functionalities is the ability to graphically show instantaneous active power, operating quadrants (Q1, Q2, Q3, Q4), as well as the status of outputs, inputs, and active tariffs.

Advanced Measurement and Safety:

The CVM-C11 is prepared to operate with Modbus RTU and BACnet communication protocols, using the RS-485 port to integrate into broader energy management systems. This makes it a perfect tool for remote control of installations and energy management automation.

This device features two relay outputs and two digital transistor outputs, configurable for alarms on any measured parameter, whether in maximum, minimum values, with hysteresis, or connection/disconnection delays. These alarms are ideal for real-time control applications, protecting the installation from hazardous operating conditions.
