Description

The multifunction electrical measurement center CMM41 can measure all parameters of the electrical network in addition to bidirectional energy. It is equipped with an RS485-Modbus communication port and an energy measurement pulse output.

Its compact design (dimensions 72×72 mm) allows it to be mounted on the front panel of cabinets and enclosures where space is limited. As an advanced digital measuring device, it can be used for special applications (such as generators, machine tools, etc.) or in energy management applications requiring the installation of multiple devices on the front panel of the same cabinet.
