DCSF01 DC Energy Meter
The DCSF01 DC electronic energy meter is a compact DC metering device integrating measurement, LCD display and communication. It measures two channels of DC voltage, current and power; supports time-of-use (TOU) tariff metering; and is equipped with two RS-485 ports that natively support both DL/T645-2007 and Modbus-RTU protocols with auto-adaptation.
Typical applications include DC charging piles, battery banks, solar PV panels and other DC systems for energy measurement. It is also suitable for DC distribution systems in industrial facilities, commercial buildings and building automation.
