Product Details
DC metering is used in specific applications to measure, collect, and store real-time data for DC power systems. Energy professionals use DC meters to monitor power generation, power usage, or to detect system faults to meet specific performance goals, reduce cost, or to verify energy integrity in their facility. It is used in various industries such as solar systems, EV charging stations, battery energy storage systems (BESS), cell towers, data centers, and light rail transportation.
The EM619002 is a DC energy meter designed to monitor and control DC power systems with a wide range of measurement parameters such as voltage, current, power and energy. The EM619002 supports bi-directional current measurement used in net metering, solar PV, and EV charger station as well as other applications such as transportation systems, telecom towers, power distribution systems, and IT networks. The meter has an RS485 communication interface and supports Modbus-RTU protocol and DLT645 protocol at the same time. It can also be equipped with digital inputs for switch monitoring, relay outputs for remote control, and an over-range alarming.
