Energy Measurement and ManagementME172 – single-phase meter is used formeasurement and registration of activeenergy and demand in single-phase two-wirenetworks for direct connection. The meteringand technical properties of the metercomply with the EN 50470-1 and EN 50470-3European standards, classes A and B, as wellas with the IEC 62053-21 and IEC 62052-11(former IEC 61036) international standardsfor electronic meters of active energy forclasses 2 and 1.The meter is designed and manufactured incompliance with the ISO 9001 standard.ME172Single-phase meterActive energyMaximum demandOne or two energy flow directions or alwayspositive registrationMultirate registrationInternal real-time clock (RTC)Load profile registration (2-channel)Measurement of current, voltage andfrequencyRS485 interface (option)LCD with No-power reading optionOption: Pulse output (kWh) or tariff output• Compact meter case with IP54 protection• Antifraud protection• Measurement of current, voltage and frequency• Indications of meter operation status• Optical port• Single-wire meter (option)• Two metering elements (option)• Load profile registration in 2 channels (option)

ME172FUNCTIONAL AND TECHNICAL DATAME172 single-phase meter is intended for residential and small commercial users. It is used formeasurement and registration of active energy and demand in single-phase two-wire networksfor direct connection.Measuring and registration:– One energy flow direction (import)– Two energy flow directions– Always positive (absolute registration)Accuracy / calibration: Due to the long-term metering stability there is no need for metersrecalibration in their life.Antifraud protectionu Absolute energy measurement (option)u Metering element in neutral circuit (option)u Single-wire measurement (option)u Reversed energy flow detectoru Meter cover opening detectoru Terminal cover opening detectoru External magnet field detectoru Hardware and software protection for programmingIndications:LED (red): kWh impulsesBlinking: load current is higher than the starting currentLit: voltage applied to the meter, load current is smaller than the starting currentTurned-off: no voltage applied to the meterCommunication:Optical port IEC 62056 – 21: for local meter programming and data downloading.Serial interface RS485 (option)Multirate registration:Internal time switch.
