The PLM-305 power measurement device is designed for 230/400 V 3-phase networks (4 conductors). Currents can be measured, up to 10A with direct measurement, or higher in conjunction with …/5A current transformers. The transformation ratio of the current transformer in use can be set in the menu. For fast energy analysis, the measured values are recorded more or less in real time. The measuring instrument is installed in the DIN rail enclosure from the Railtec B series, 6 modules, by OKW.
