Product Description

The CVM-B100 and CVM-B150 units are panel mounted three-phase power analyzers (dimensions: 3.77″ x 3.77″ and 5.66″ x 5.66″, 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.

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-CVM- AB-Datalogger module. Enables direct monitoring of the historical data stored in the unit via a conventional web browser.
