See this document.) APPLICATIONS The MID1 certified energy meters included in the ENERGYMID product range are used to acquire and bill active energy in industrial, household, commercial and building management applications. Integrated 4-quadrant measurement permits measurement of energy import and export. 4 tariffs (hardware-controlled as standard feature) and, depending on model or version, 4 additional tariffs (software-controlled) can be selected. In combination with national approval of the integrated load profile (Z2) in accordance with PTB-A 50.7, this energy meter is also suitable for fulfilling legal energy requirements. Energy data are transmitted to superordinate management systems via various communication interfaces, e.g. for acquisition and optimization, as well as for building automation and control technology. Thanks to simple installation including detection of connection errors and flexible configuration options, it performs all measuring tasks highly proficiently.

Simply and conveniently specify the technical characteristics and other functions (e.g. pulse output, bus connection type and load profile) for your ENERGYMID energy meter via configurable features when placing your order – you get an individualized, device-specific variant which is perfectly matched to your needs. MULTIFUNCTIONAL VERSION Depending on the type of multifunctional variant, the meter is also capable of acquiring reactive power and indicating up to 33 additional measured quantities directly at the display. Voltage level, utilization of individual phases, reactive power component...
