Single-phase electric energy meter EM619001

DIN railRS-485with built-in communication

Product Details
There are 4 models of DC meter: EM613001/EM619001/EM619002/EM613005. EM series DC energy meters are designed for measuring and monitoring in DC systems. The DIN-rail DC meters measure key DC parameters: voltage, current, power and energy, and support bi-directional measurement. Data access is via RS485 (Modbus RTU / DLT645). Units accept AC/DC or DC power supply, input voltage up to 1000 VDC, and current via external shunt. Multi-tariff versions include RTC for tariff scheduling and monthly records.

Product Overview
EM619001 is intended for monitoring and control of DC installations, including PV string and battery systems. It supports limit alarms, analog output, digital input, relay output and communication functions. Provides energy metering, data processing, real-time monitoring and an LCD display. Designed for high overload capacity, accuracy, low consumption and automatic data save on power loss.
