The ELITEpro XC energy data logger is a complete, portable solution for pinpointing electric usage and recording building performance metrics. It is capable of measuring, storing, and analyzing electrical consumption data which is derived from the voltage and current inputs. The ELITEpro XC portable power data logger uses direct connections to each phase of the voltage and various interchangeable current sensor options such as split-core , clamp-on, or flexible Rogowski RoCoil current transformers (designed for large loads or large cables and bussbars) to monitor current on each phase.
