ST100 is electronic meter intended for direct connection to the three-phase electrical network and measurement of active and optionally reactive electric energy in the residential applications. The meter can also be used in single-phase electrical network. All functionalities of ST100 meter are implemented in accordance to relevant standards: IEC, EN, VDEW, M-bus, DLMS...

Using the available ports: Port A (for connection with the AMM center) and Port B (for connection of the switching module), the meter is ready for integration in the AMM system (AMM ready).

By connection of the communication module (PLUG IN) to the electric port A, the meter is integrated in the AMM system. Connection of the switching module (bi-stabile switch) on the port B, which is realized according to the M-bus standard, enables the function of consumption management.

AMM system integration of the meter can be realized by simple addition of communication module and switching module under the terminal cover. There are separate places with appropriate dimensions for placing of communication and switching modules below the meter terminal cover. Connection of these modules is done through standardized electrical ports (Port A and Port B).
