Circutor Network Analyser Line-CVM-D32 System

The Circutor Line-CVM-D32 network analyser, with code M58100, is a versatile and advanced device designed for real-time monitoring and analysis of electrical parameters in single-phase, two-phase (with or without neutral), and three-phase systems, both balanced and unbalanced. This device offers a detailed and accurate view of fundamental electrical parameters, including the measurement of harmonics up to the 40th, making it an indispensable tool for efficient energy management in low and medium voltage installations.

Compact design and DIN rail mounting:
The Line-CVM-D32 is designed for DIN rail mounting, with a compact size of 52.5 x 118 x 70 mm, facilitating its integration into distribution boards where space is limited. Despite its small size, this analyser is capable of performing comprehensive and detailed monitoring of electrical variables, including voltage, current, active and reactive power, frequency, consumed energy, generated energy, and more. Its installation is straightforward, allowing for quick implementation in any type of electrical system.

Accurate and versatile measurement:
The Line-CVM-D32 is equipped with three current inputs that allow measurement through current transformers /5 A, /1 A or /250 mA, providing great flexibility to adapt to different types of electrical installations. Current and voltage measurements are performed in true root mean square (True RMS), ensuring optimal accuracy even in electrical systems that are not perfectly sinusoidal. Furthermore, it can measure energy in four quadrants, meaning it can monitor both consumption and generation of energy, ideal for applications in self-consumption systems with renewable sources.

Advanced communication and modularity:
This analyser has communication features via the Modbus/RTU protocol through an RS-485 port, allowing its integration into energy management systems and connection to centralised monitoring platforms. Additionally, the Line-CVM-D32 is modular and expandable, meaning expansion modules can be added to increase its functionalities, such as additional inputs and outputs (transistors, relays or analogue), and the ability to convert any measured electrical parameter into analogue signals. This offers enormous flexibility and adaptability to the specific needs of each installation.

The device features two opto-isolated transistor outputs, fully configurable, allowing pulse generation for active or reactive energy monitoring, and can act as programmable alarms on any electrical parameter with delay in connection or disconnection. These features make it ideal for applications where precise control of energy consumption and quality is necessary.

Advanced applications:
The Line-CVM-D32 is ideal for use in distribution boards and incoming lines where a DIN rail-mounted analyser is required. Its ability to measure harmonics up to the 40th makes it an essential tool for energy quality supervision, allowing the identification of harmonic distortions that can negatively affect the performance of electrical equipment. Additionally, it is capable of recording power quality events, such as overvoltages, sags, and interruptions, providing a complete view of the electrical network state.

Highlighted technical features:

• Nominal voltage: 300 V L-N / 520 V L-L, with an input impedance of 1 MΩ, ensuring precise measurements in three-phase networks.
• Current and voltage measurement accuracy: Class 0.2%, guaranteeing high accuracy in measuring electrical parameters, even in unbalanced networks.
• Active energy measurement (kWh): Class 0.5S for current transformers of /5 A, ensuring correct billing of energy consumption.
• 1.77" TFT display, facilitating clear data visualisation, complemented with 2 LED status indicators.

Installation and durability:
This analyser is designed for simple installation on DIN rail according to IEC 60715 standard, ensuring compatibility with a wide variety of electrical panels. It is manufactured with a V0 self-extinguishing plastic housing, ensuring resistance to potential fires. Additionally, it has a protection degree of IP30 and IP40 on the front, suitable for indoor use.

The Line-CVM-D32 has an operating temperature range between -10°C and +50°C, and can withstand a relative humidity of up to 95% without condensation, making it suitable for use in a variety of industrial and commercial environments.

The Circutor Line-CVM-D32 network analyser is a complete solution for electrical network monitoring, providing a precise and flexible tool for energy management and control in installations where space is limited.
