The calibrated, compact energy meters included in our Compact Line product range can be used to acquire and bill active energy in industrial, household, commercial and building management applications.

Relevant values are transmitted to data logging, billing and optimizing systems, as well as to building automation and control technology applications, by means of 2 pulse outputs or the integrated infrared interface and an external interface module. Modbus, M-Bus and Ethernet are currently supported.

Two S0 Pulse Outputs

The meter also measures all of the electrical system’s essential parameters and makes them available via the infrared interface. Energy and instantaneous power values appear directly at the display.
