Three-phase Multifunction Power Meter
The MDM300 series is a three-phase multifunction power meter featuring programmable measurement, remote digital communication and control, energy pulse output, over-limit alarm, multi-rate energy metering, and voltage sag detection. It is suitable for continuous monitoring and control of power distribution systems and can serve as a remote terminal unit (RTU) for SCADA and energy management systems.
