Three-phase modular smart meter for industrial and commercial consumers

ST300 is three-phase modular smart meter designed for measurement of active and reactive energy of commercial and industrial consumers, with direct, semi-indirect and indirect grid connection. ST300 can also be used in single-phase networks. AMI system integration is enabled by connecting optional plug-in communication module (CMxyS – PLC or GPRS/3G communication) and switching module (SD30S) via M-Bus connection. Both plug-in modules are simply mounted under the terminal cover. ST300 is compliant with all relevant standards and regulations.
