Description

The multifunctional electrical network analyzer CMM61 can measure all parameters of the electrical network in addition to bidirectional energy. It is equipped with an RS485-Modbus communication port, an energy measurement pulse output, as well as one relay output and two digital inputs for monitoring the measured departures. It is designed to be mounted on the front panel of cabinets and adopts an ultra-slim design both on the front and back (total thickness less than 40 mm), in addition to being easy to install. As an advanced digital measuring device, it can be used in monitoring and supervising electrical installations as well as in electrical energy management systems. The device exists in two versions. One version is the standard CMM-61C equipped with current measurement inputs up to 5A, usable with traditional current transformers (ratio /1A or /5A). The other model is the CMM61-R, which is equipped with current measurement inputs suitable for flexible current sensors (Rogowski coils).

The CMM-61R is therefore the ideal solution for energy management system implementation projects in existing installations that cannot tolerate power interruption.
