Modular smart meters


Three-phase modular smart meter for residential, commercial and industrial consumers

ST310 is three-phase, MID-certified, modular smart meter designed for the measurement of electrical energy of residential, commercial and industrial consumers, with direct or transformer grid connection (CT or CT/VT). AMI system integration is enabled by connecting plug-in communication module (CMxyS – PLC or cellular communication) and switching module (SD30S). Replaceable communication module offers seamless communication options and allows easy future upgrade of communication technology by simple modem replacement without need for removal of metrology seals. Both plug-in modules are mounted under the terminal cover. ST310 version for direct grid connection is equipped with Port B for connection of the switching module and realization of load management functionality. ST310 is available in versions without communication and/or switching modules. All ST310 functions are compliant with the following standards and regulations: IEC 62052-11, IEC 62053-21/22/23, EN 50470-1/3 (MID), M-Bus and DLMS/COSEM.
