It measures the energy, which circulates in each phase of a three-phase magnet, it communicates using an RS-485 cable, it is self-powered and may be connected to the rest of the CcM electronic devices.
CcM4 smart meter for submetering is one of the devices from the CcM product family designed to measure electrical parameters (voltage, current, energy, harmonics, etc.) in three-phase installations with a neutral wire.
The CcM smart meter consists of a set of devices used for the monitoring of electrical parameters inside the electrical switchboard in single- and three-phase installations. They are best suitable for installation in thermal-magnetic switches or residual-current circuit breakers to obtain multiple measures in multiple points and to be physically interconnected using a 485 cable to a sub-metering design.
CcM4 smart meter, in particular, is one of the “principal” CcM smart meter (CcM4, CcM3 and CcM2). Their function is two-fold. To work as a slave of the general master (PLC or PC, Windows/Linux or CcMaster) inside the principal bus and as a master inside the secondary bus, commanding other devices of the CcM smart electricity meter – CcM1 slaves (secondary devices).
The user is able to access the data from CcM4 smart meter through an RS-485 communication cable, using Modbus RTU protocol or through one of the software tools offered free of charge, such as CcManager (configuration, viewing and storing in a local network or via a PLC window, Linux or directly with the CcMaster) or the Energy CcM web portal (viewing and storing data in the cloud through CcM-WiFi ).
It is also possible to add the CcM-WiFi peripheral to obtain data through a WiFi network (see the manual of CcM-WiFi, available on this website) and enable wireless communication with the device. The best way to configure a WiFi device from the CcM smart meter home display is using the EnergyCcM App or by accessing the internal website of the WiFi device using its address.
As it can be combined and used with different devices within the product range, the CcM smart meter product home display offers multiple configuration options and allows users to configure the most convenient solution for both, their domestic and industrial installations. Installations can be wireless or connected with a communication cable. The devices to domestic energy control, can be connected to each other and create communication buses, establishing configurable master-slave hierarchies.
CcM4 smart meter for submetering, for instance, behaves similarly to an energy meter or a grid analyser. Inserted directly into a thermal-magnetic switch or a residual-current circuit breaker, the device is connected in series with the consumption line, registering voltage, intensity, power, active and reactive energy as well as harmonics in each of the phases.
