2. PRODUCT DESCRIPTION
The CVM-C11 device measures, calculates and displays the main electrical parameters of the following
networks: single-phase, two-phase, with and without neutral, balanced three-phase, with ARON meas-
urements or unbalanced. The measurement will be taken in RMS with the three AC voltage inputs and
four current inputs.
There are 4 versions of the device, depending on the type of current input:
CVM-C11-ITF-IN-485-ICT2 and CVM-C11-ITF-IN-ETH-ICT2 model measures current through /5A
or /1A transformers.
CVM-C11-FLEX-IN-485-ICT2 current measurement through Rogowski sensors.
CVM-C11-MC-IN-485-ICT2 indirect current measurement with efficient transformers of the MC1
and MC3 series.
The device features:
- 3 keys that allow you to browse between the various screens and program the device.
- 2 indicator LEDs.
- LCD display, displays all parameters.
- 2 digital inputs, used to select the tariff, detect the logic state of external signals or to gen-
erate a synchronism pulse to calculate the maximum demand.
- 2 digital outputs, fully programmable.
- 2 alarm relays, fully programmable.
- RS-485 Communications, with two serial protocols: MODBUS RTU© and BACnet.
- Ethernet Communications (CVM-C11-ITF-IN-ETH-ICT2 Model), with two serial protocols:
MODBUS TCP and BACnet IP.
