The MULTICUBE 950 is a Din 96mm three line display, powerful and extremely cost effective “3 in 1” metering solution, monitoring 3 x 3 phase loads (3 wire or 4 wire) or, 9 x 1 phase loads or a combination of them, for example 2 x 3 phase loads and 3 x 1 phase loads.
Cost effectiveness per meter point is further enhanced by just one voltage and comms connection per MULTICUBE 950. Further time savings come from the “Plug & Play” RJ12 to RJ12 CT adaptors, included as part of the kit. Each three 333mV secondary CT kits are supplied with their secondary tails already terminated into the adaptor and the RJ12 cables do the rest. In the case of single phase loads three loads go to one adaptor.
The MULTICUBE 950 also features innovative “Auto CT Recognition”, this avoids errors from programming the CT primaries incorrectly by automatically recognising the CT primaries for you. Additionally, “Auto CT Rotation” compensates for CT’s installed the wrong way round. Plus “Auto CT Accuracy Compensation” guarantees the accuracy of your data, the meter will compensate for any phase angle errors in your CT’s, giving peace of mind that 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 CT’s on the wrong phases (CT’s not in phase). Should this occur a warning on the meter’s large backlit display comes up informing there is an error.
The very powerful MULTICUBE 950 also packs in demands and alarms as standard and fast communication options allow up to 20 reads every second. The fast MODBUS RTU option also provides aggregated “3 in 1” data and optional 100mSec reading updates. Also included is a MODBUS test facility to test the integrity of the MODBUS wiring.
The MULICUBE 950 auto scales to Wh, KWh, MWh etc, depending on the CT ratio programmed. The MULTICUBE 950 is able to accept a very wide voltage input span of 80-480V L-L or 46-277V L-N, thus enabling the CUBE 400 to be used on VT circuits such as 11KV/110V, therefore a VT ratio can also be programmed if required.
