INFORMATION

Description

The CVM-B50 is a panel-mounted power analyzer (96 × 96 mm) with energy logging, downloadable memory, and integrated web server. It allows start-up via the app or web server without additional software and features an automatic wiring error correction system for simple installation.

Ideal for analysing electrical variables and consumption quality, including voltage and current THD%, as well as individual phase harmonics up to the 31st order. Neutral current measurement enables detection of imbalances and potential neutral conductor overloads.

Compact and versatile, it performs four-quadrant measurements (consumption and generation), suitable for both Medium and Low Voltage installations.

Characteristics of the device

  • 40 days of built-in downloadable memory in CSV (mobile or PC)
  • Configuration, display and start-up via app or web server
  • Neutral current measurement
  • THDU%, THDI%, and harmonics (up to 31st order)
  • Automatic Autowiring system (wiring error correction)
  • Wi-Fi and Ethernet communications (Modbus TCP/IP)
  • 4 inputs, 2 relay outputs, and 2 digital outputs
  • User-defined screen creation with selected variables
  • Display of active quadrant and power usage percentage
  • Current measurement via .../5 A, .../1 A, .../250 mA or flexible clamps (depending on model)
  • On-screen indication of the status of outputs, inputs and/or active tariff.

Applications

The CVM-B50 is specially designed to analyse changes in electrical variables, detect network harmonics, and measure energy, facilitating energy audits in accordance with ISO 50001 or obtaining CAE certification in the Spanish market.

Neutral current measurement allows the detection of circulating currents that may cause issues in the installation. The device can be integrated into SCADA systems for remote management and monitoring via Wi‑Fi or wired Ethernet connection.

It features digital inputs for logging consumption from other meters via pulses, detecting the status of installation sensors, or distinguishing consumption by tariff. Additionally, the digital outputs allow automation of the installation through open/close commands based on any measured instantaneous value.
