EM133
TOU Revenue & Power Meter
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.
