CVM-B50-ITF Power Analyzer
The CIRCUTOR CVM-B50-ITF is a compact 96 x 96 mm panel-mounted power analyzer for energy measurement, power quality visibility, downloadable data logging and remote monitoring.
It supports Ethernet, Wi-Fi and Modbus TCP/IP integration, making it suitable for SCADA, BMS, EMS and IoTWatt 4.0 projects where fixed panel metering must be connected directly into a digital monitoring platform.
Product Overview
The CVM-B50-ITF is designed for installations requiring more than basic energy metering. It measures electrical variables, energy consumption, generation, voltage and current distortion, individual harmonics up to the 31st order and neutral current.
The analyzer includes downloadable memory, an integrated web server, app-based configuration and automatic wiring-error correction. These features help reduce commissioning time and make the device practical for fixed monitoring at main panels, sub-panels, MCCs and energy management points.
Key positioning
CVM-B50-ITF is suitable when a compact fixed meter must provide local display, remote access, downloadable data, harmonic visibility, neutral-current monitoring and Modbus TCP/IP integration.
Typical Monitoring Architecture
CVM-B50-ITF measures electrical parameters at the panel and sends data through Ethernet or Wi-Fi using Modbus TCP/IP to SCADA, BMS, EMS or IoTWatt 4.0.
