Model SMV and SMVQ - Universal Compact Power Meters
From Panel Meters
Universal compact power meters combine accurate 3-phase energy and power measurement with data logging, power quality analysis. Includes also advanced programmable alarms and general input/output capabilities. Compact universal PQ analyzers SMV and SMVQ are similar to the SMP resp. SMPQ instruments with the only difference being its bright segment LED display. Large internal memory allows continual measurement and datalogging of all important parameters for a relatively long time. An important part of this compact platform is an embedded four-quadrant electricity meter with automated meter reading archive. SMV and SMPQ meters are a class S power monitoring device according to the international standard IEC 61000-4-30 ed. 2. SMVQ additionally evaluates and archives all required power quality and distrubance data according to EN 50160 standard.
