100% electronicThe main advantage of the NCS range of sensors is that they are designed using a brand-new solution: 100% electronic technology. Unlike other currently available solutions such as shunts and CTs, this approach means that these sensors are very compact. Several patents were necessary to achieve this improvement.Considerable energy savingsNCS sensors offer considerable savings in energy. Indeed only a few watts are required to power the NCS sensor in contrast to T
