CVM-C5 Multifunction Multimeter
The CIRCUTOR CVM-C5 is a compact 96 x 96 mm panel-mounted multifunction multimeter that records energy values and supports four-quadrant measurement for consumption and generation.
It is suitable for low-voltage installations in three-phase 3-wire, three-phase 4-wire, two-phase, single-phase and ARON connection applications. The CVM-C5 is a practical option for panel metering, energy cost visibility, CO2 indication and Modbus-based energy monitoring.
Product Overview
CVM-C5 is designed for electrical panels that need a compact meter with clear local display and energy-value recording. It shows electrical parameters, energy consumption, cost per kWh, kgCO2 consumption / generation and operating hours for preventive maintenance reference.
The meter supports different current input versions, including conventional .../5 A or .../1 A CT inputs, CIRCUTOR MC efficient current transformer inputs and .../333 mV transformer inputs. This allows the correct model to be selected based on the site metering architecture and CT type.
Key positioning
