DTSD1352-4S AC multi-channels energy meter is mainly used for the full electric parameter measurement of multiple circuits with 9-30V working power supply. It can access the current input of up to 4 three-phase circuits or 12 single-phase circuits at the same time. It has RS485(Modbus-RTU) and Ethernet (Modbus-TCP) communication. The meter supports external RJ12 split core current sensor access or Rogowski coil(output current 100mV/333mV). It has been widely used in many projects of American Tower, TASC Towers, Helios Towers, IHS Towers, Orange, Edgepoint, and others.
