Description

The CVM-B100 and CVM-B150 units are panel mounted three-phase power analyzers (dimensions: 96×96 and 144×144 mm, respectively). Both offer 4-quadrant measurement (consumption and generation). Suitable for Medium or Low voltage installations, in both 3 or 4-wire three-phase circuits, two-phase circuits with or without neutral, single-phase circuits or ARON connections.

The CVM-B100 and CVM-B150 high-performance units feature a measurement engine that allows the user to analyse many different electrical parameters, in addition to offering a large variety of optional expansion modules for the same unit.

Features:

• Format: 96×96 (CVM B100) and 144×144 (CVM B150)
• High-resolution VGA colour screen
• IP 65 front panel protection (with sealing joint)
• 5 voltage inputs (3 phases + neutral + earth) 1000 V_f-f
• 4 Current inputs, ITF
• Class 0.2 voltage and current accuracy
• Class 0.5S energy accuracy
• Expandable unit, up to 4 modules, combining digital and analogue outputs, Modbus/TCP, MBus, LonWorks, Profibus, XML/Web
• Modular (optional addition of expansion modules)
• Touch-sensitive movement buttons
• Universal power supply source
• RS485 communications port (Modbus/RTU and BACnet protocols)
• Customisation of parameters to be displayed
• Operating hour indicator for preventive maintenance.

Other features:

• Innovative SCV interface (Slide, Choose & View) for versatile data display, enabling the customisation of the parameters displayed on the screen
• Electrical parameters: instantaneous, maximum, minimum (with date and time) and demand
• Incremental electrical parameters (energy), times, costs, emissions
• 3 Tariffs (can be selected via the digital input or RS485 communications)
• Capable of showing costs and kgCO₂ emission sources on the screen, depending on the energy consumed or generated
• 2 Relay outputs for alarms with delay, times, ON and OFF, etc.
• 2 transistor outputs for alarms or impulse generation, with all the possible configuration parameters
• 2 digital inputs, with control over the selection of the unit’s tariffs or configurable for monitoring purposes, with RS-485 Modbus communications, monitoring of logical states of other electromechanical units. (RCCBs, thermal-magnetic circuit breakers, etc.)

Applications

• Control and monitoring of all electrical parameters measured in any electric distribution panel and low and high-voltage connection points.
• 4 alarms (2 per transistor and 2 per relay), fully and independently programmable: low or high value, hysteresis, connection/disconnection delays, normally open or closed standby status and interlocking.
• Generation of impulses with transistor outputs, fully and independently configurable over any incremental parameter (energy, costs, kgCO₂, total meter or tariff hours)
• Transducer that converts analogue signals to any instantaneous parameter that the unit can measure or calculate, with built-in expansion modules with analogue outputs.
• Display of process signals, with a built-in expansion module with analogue inputs; optional reporting of these signals to SCADA systems through communication systems
• Control of electrical load or alarm signal operations by programming the transistor or relay outputs that are built-in or added through expansion modules.
• Autonomous datalogger with web server, connected to a M-CVMAB-Datalogger module. Enables direct monitoring of the historical data stored in the unit via a conventional web browser.
