Schneider Electric PM820UMG Power Meter 3 Phase

The Schneider Electric PM820UMG Power Meter is a three-phase power monitoring device in the PowerLogic PM800 series designed to monitor electrical parameters across three-phase power distribution networks, delivering precise measurements of voltage, current, power, energy consumption, and power quality without a local display for remote monitoring. It requires external current transformers for current sensing and communicates via RS-485 Modbus to access data from building management or industrial monitoring systems. With a voltage measurement range up to 690 V AC, a supply voltage of 100–415 V AC or 125–250 V DC, and a frequency range of 45–65 Hz, it is built for harsh environments in manufacturing plants, data centers, electrical distribution panels, and utility monitoring installations, featuring IP52 front panel protection when mounted. Applications include energy management, electrical load analysis, and integration into industrial power monitoring and building management systems.
