The TNM300 is a universal multifunctional meter with 12 channels, each with three phases. By using one TNM300 energy and power meter, the use of 11 additional energy meters or multifunctional meters can be saved, making the working environment clearer and space-saving, as the TNM300 energy and power meter covers the capacity of 12 energy meters or multifunctional meters. It has an RS485 and TCP/IP interface with the BACnet and Modbus protocols. The meter can be operated and configured via the TCP/IP interface using a web browser. An indispensable aid for any energy management system for displaying the minimum and maximum values, as well as the active and reactive power and all important measured variables.
