Multi-function Power Meter

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.
