Three-phase network analyzer panel Circutor CVM-C11-ITF-IN-485-ICT2

The Circutor CVM-C11-ITF-IN-485-ICT2 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 for both energy consumption control and monitoring of generated energy.

Main features:

This analyzer is capable of measuring and recording 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 energy quality in the installation. Additionally, the CVM-C11 includes the ability to measure neutral current, which is essential for detecting imbalances in the system and possible overloads of the neutral conductor.

The panel design facilitates its integration into any electrical installation, and its graphical interface with a backlit LCD screen provides a clear visualization of data, allowing the user to configure the display of parameters according to their needs. Among the advanced visualization features is the ability to graphically display 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 ready 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 automation of energy management.

This device features two relay outputs and two transistor digital 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.
