SATEC EM133 is a multifunction power meter, ideal for a wide range of applications such
as revenue metering, industrial power monitoring and for interfacing SCADA in utility
substations.The EM133 can be fitted with a wide range of communication interfaces and I/O
extensions, making it a cost-effective combination of a power meter, smart transducer and
PLC controller. MID certified for revenue metering, it is designed for DIN-rail mounting,
equipped with built-in communication ports, digital I/Os and anti-tamper enclosures.
