The MultiCube 950mV is a powerful and extremely cost effective, 3in1 metering solution, designed to meet the requirements of both energy managers and electrical engineers. As well as measuring 3X the loads of a standard sub-meter, in any combination of 3ph/1ph, the MultiCube 950mV also packs in market leading innovations, with Accuracy Class 0.5 standard, and Class 0.2 optional. In addition to very competitive pricing per meter point is the reduced cost of just one voltage and comms connection per MultiCube. Further savings come from the 'Plug & Play' RJ12 to RJ12 CT adaptor, included in the price, with just one to plug in for each 3ph load or set of 3 X1ph loads making installs even quicker. The MultiCube also features innovative, patented, Auto CT Recognition. This avoids errors from programming the CT primaries incorrectly by automatically recognising the CT‘s primary for you; plus Auto CT Rotation - to compensate for CTs installed the wrong way round; and Auto CT Accuracy Compensation - guaranteeing the accuracy of your data. This means that you will know the combined accuracy of the MultiCube 950mV and CTs because the MultiCube can compensate for the phase angle of our CTs giving you peace of mind that your data will not contain any hidden inaccuracies. Further safeguards against error are provided by the RJ12 plugs that cannot be installed the wrong way round. This just leaves the possibility of installing the CTs on the wrong phases, and for this the MultiCube950mV provides a warning on its large, backlit display so that costly returns to site can be avoided. To provide the ultimate in flexibility for installation, our comprehensive range of mV CTs and Rogowski Rope CTs can be used in any combination required, on the same MultiCube 950mV, across each 3ph load or group of 1ph loads. We have also included a MODBUS test facility to test the MODBUS wiring. Covered by ND’s industry leading 5 year warranty, and accredited for CE, CB, UL, CUL and CTick this is the ultimate fit & forget submetering solution. But the very powerful MultiCube also packs in demands and alarms as standard and fast communication options that allow up to 20 reads every second. The fast Modbus RTU feature also provides aggregated 3in1 meter data and optional 100mS reading updates for truly responsive remote measurement. The MultiCube950mV is a highly accurate, 3 in 1 energy management sub-meter that provides a powerful platform to analyse power quality with options of THD and Individual Harmonics to the 63rd, and an optional Virtual Summating or Residual Meter. The Virtual Meter provides a full set of power and energy measurements (apart from power quality) and can be configured, by the user, to provide the SUM of measured loads, thus saving the cost of an additional incomer meter; or can be configured to detect the incoming power, and subtract the other measured sub-loads, to provide a Residual Meter point for the total of all those insignificant loads which normally go unmeasured.
