1 /3.15 Professiona energy meter for 2, 3, 4 wire systems with 65 A direct connection or 1 A, 5 A transformer connection Accuracy cass B for commerce and industry and for enhanced requirements in private househods Cost savings thans to initia caibration ex factory, per MID, conformity evauation procedure for modues B+D Configurabe mutifunctiona versions for the acquisition of reactive energy and measured ine quantities Indication of instaation errors: phase sequence, phase faiure, transformers with reversed poarity, overoad Universa puse output with adjustabe puse rate, puse duration and seectabe votage range Fexibe communication via integrated ON, M bus or bus interface Possibiity to maintain fu functionaity via fai-safe 24 V auxiiary votage system even if disconnected from the mains Cover can be seaed, parameter configuration oc Quaity product Made in Germany -Bus EB 8 Appications The caibrated energy meter can be used for the acquisition and biing of active energy in commerce and industry, househods and faciity management. The measured vaues are transmitted to data ogging, biing and optimization systems as we as buiding automation and C&I systems via puse output, ON, M bus or bus interfaces. Instaation is absoutey simpe as the meter automaticay recognizes fase connections and signas them immediatey. The active power dispay offers a maximum of operating convenience as it immediatey informs about the momentary oad of the eectric circuit. And if you wish to have more information about your mains system, just extend the range of functions. Appicabe Reguations and Standards IEC/EN VDE 0470, part 1 Degrees of protection provided by encosures (IP code) DIN Eectrica power meters, muti-rate tariff switches and rippe-contro receivers DIN EN VDE DIN EN VDE DIN EN VDE DIN EN Puse output devices for eectromechanica and eectronic meters Eectricity metering equipment Part 1: Genera requirements, tests and test conditions Metering equipment EMC requirements Part 3: Particuar requirements Static meters for active energy (cass indexes A, B and C) Eectricity metering equipment (a.c.) - Particuar requirements - Part 23: Static meters for reactive energy (casses 2 and 3) Mutifunctiona Design Depending upon the type of mutifunctiona design, the meter is aso capabe of acquiring reactive energy and of indicating up to 26 additiona measured quantities. With a simpe eystroe and without the use of additiona measuring equipment, it is thus possibe to evauate the votage eve, the capacity utiization of the individua phases, the reactive power component and the function of reactive power compensation equipment at any time. Pease refer to the tabe beow for detais.
