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.
