Single Phase Kilowatt Hour Meters | UEC80-2 & UEM80-2

Two Din module kilowatt hour meter for basic energy measurement in residential and commercial single phase applications. Includes the option for built-in communications via an integrated RS-485 serial connection for either Modbus-RTU or M-Bus. Available with either a resetable (MID) or non-resetable kWh counter.

Besides the energy, the meter can measure the main electrical parameters and makes them available on the built-in COM port. The LCD display shows the energies and the instantaneous powers. The COM port allows to manage the connected meter by a remote station. Data is transmitted on an RS-485, M-Bus or Ethernet line according to the device model for monitoring and historical data logging by an energy management system (EMS).

Furthermore, dedicated applications for remote management can be provided including:

• Modbus Master software > for energy meter management by PC in RS485 Modbus network.
• M-Bus Master software > for energy meter management by PC in M-Bus network.
• Web server > built-in interface for energy meter management by PC in Ethernet network. Moreover, it allows to enable a data recording and a manual or automatic data transferring (in the case of automatic transferring, data is sent to a remote server at the set time schedule).

The meter is built according to EN 50470-1 standard. The active energy is compliant to IEC/EN 62053-21 class 1, but for MID certified device it fulfills class B requirements according to EN 50470-3. The accuracy of reactive energy is compliant to IEC/EN 62053-23 class 2.

Wide backlighted LCD display with clear graphic symbols comprehensible at a glance. Metrological LED on front panel and sealable terminal covers. The analysis of the MTBF values, the accurate selection of components and the reduction of the internal working temperatures together with strict production and control standards guarantee a product of excellent quality and long lasting reliability.
