Multifunction meters – 12 channels of 3 phases
Basic data
The TNM300 is a universal multifunction meter with 12 channels of three phases each.
By using one TNM300 energy and power meter, the application of 11 other energy meters or multifunction 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 multifunction meters.
It has RS485 and TCP/IP interface with BACnet and Modbus protocols. The TCP/IP interface allows the meter to be operated and configured via a web browser. An indispensable aid for any energy management to display min. and max. values, as well as active and reactive power and all important measured variables.
