CVM-C11 Power Analyzer
Compact 96 x 96 mm panel-mounted power analyzer for energy monitoring, power quality visibility, harmonic analysis, tariff discrimination, alarm outputs and RS-485 / Ethernet integration.
Compact Analyzer for Energy and Power Quality Visibility
The CIRCUTOR CVM-C11 is a compact panel-mounted power analyzer designed for electrical panels where energy visibility, harmonic monitoring, demand tracking, tariff allocation, alarm outputs and digital integration are required. It supports 4-quadrant measurement, making it suitable for both consumption and generation monitoring applications.
The analyzer can be applied in low-voltage and medium-voltage systems through CT and VT connections, supporting applications such as main incomer monitoring, sub-metering, generator/PV segregation, power quality checks and digital energy audit data collection.

Power Quality Visibility
Displays voltage/current THD% and individual harmonics up to the 31st harmonic.
Digital Integration
Supports RS-485 Modbus/RTU and BACnet communication for BMS, EMS, SCADA and IoTWatt 4.0 integration.
Typical Data Flow
CVM-C11 converts panel-level electrical measurements into useful operational data for dashboards, reports, alarms and energy improvement actions.
