ND Cube 350 is a cost effective kWh and kW panel mount meter, which has pulsed outputs and accuracy better than class 1. It also features 'Right First Time' installation aids (kW display, CT, VT and Pulse value displays) that clearly show if the meter had been wired and programmed correctly. These features make this meter suitable for control panels and switchboards.
The IP communications feature allows for Pulse or Alarm outputs, allowing for a more accurate and secure way to manage energy usage. The variety of TCP/IP protocols make this meter very accessible through direct communication with energy management software and building control solutions, without the need for data loggers or concentrators. The web pages on the IP labelled Cube 350-IP allows the user to view important instantaneous values and access the setup pages to change parameters.
