Product Description

The Circutor CVM-B50 is a three-phase power analyzer and multifunction electrical energy meter designed for panel-door installation in switchboards, distribution panels and electrical monitoring systems. The CVM-B50 provides a complete view of electrical consumption and power quality parameters, measuring voltage, current, active power, reactive power, apparent power, power factor, frequency, energy and harmonic distortion from a single compact panel-mounted instrument.

Designed for three-phase electrical systems, the Circutor CVM-B50 displays electrical measurements directly on its high-contrast backlit display, allowing operators, electrical contractors and energy managers to view measurements locally at the switchboard without requiring a laptop or external monitoring system. The display provides information for the three phases and total values, making it suitable for day-to-day electrical inspection, energy monitoring and troubleshooting.

The CVM-B50 supports measurement of phase-to-phase and phase-to-neutral voltages, currents, active power, reactive power, apparent power and power factor, together with frequency and harmonic measurements. Its harmonic analysis and THD measurement capabilities help identify electrical distortion and assess the quality of the power supply, particularly in installations containing variable speed drives, rectifiers, power electronics, UPS systems and other nonlinear loads.

A key feature of the CVM-B50 is its ability to measure four-quadrant energy, allowing imported and exported energy to be monitored separately. This makes the analyzer suitable for installations where electrical energy can flow in both directions, including solar PV systems, generators, renewable energy installations, energy storage systems and sites with both consumption and generation.

The CVM-B50 also provides Modbus communications, enabling measured electrical parameters to be transmitted to an energy management system (EMS), building management system (BMS), SCADA platform, PLC or other industrial monitoring software. This allows the device to function as both a local panel meter and a data source for centralized energy monitoring and reporting.

The analyzer is designed for panel-door mounting, making it particularly suitable for electrical switchboards and distribution panels where space is limited and measurements need to remain visible to operators. Its rear connection terminals keep wiring behind the panel while the display and navigation controls remain accessible from the front.

The CVM-B50 is suitable for sub-metering, energy monitoring, load profiling, power factor monitoring, harmonic monitoring, electrical distribution monitoring, energy cost allocation and ISO 50001 energy-management applications.

For commercial buildings, industrial facilities, data centres, utilities, manufacturing plants, water and process facilities, solar installations and other energy-intensive sites, the CVM-B50 provides a practical way to understand where electrical energy is being consumed, how equipment is loading the supply and whether power-quality issues are affecting the installation.

Typical Applications

Sub-Metering
Install the CVM-B50 on a factory line, building tenancy, HVAC system, production area or other electrical load to measure actual energy consumption rather than relying on estimated or aggregated data.

Energy Cost Allocation
Measure individual feeders, departments, production lines or tenants to determine how electricity consumption is distributed across a facility.

Four-Quadrant Energy Measurement
Monitor both imported and exported energy in installations with generation, such as solar PV, generators and renewable energy systems.

Power Factor Monitoring
Monitor power factor alongside voltage, current and power to identify inefficient electrical loading and potential reactive-power issues.

Harmonic and THD Monitoring
Use harmonic measurements to identify electrical distortion caused by nonlinear loads, variable frequency drives, rectifiers, UPS equipment and power electronic devices.

Centralized Energy Monitoring
Transmit measurements through Modbus to an EMS, BMS, SCADA system or industrial energy platform for centralized monitoring, dashboards, reporting and analysis.
