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.
