Multifunction meters
Basic data
The TNM96 is a compact, highly accurate 0.2% (0.1 optional), three-phase multifunction meter with additional CT input for differential current measurement.
It includes energy consumption recording and supports BACnet and Modbus protocols. The meter can be operated and configured via a web browser using the Ethernet TCP/IP interface.
An indispensable aid for displaying and evaluating via additional software the min/max values, active, apparent and reactive power, and harmonics up to 64en, as well as all important measured variables.
