DENT Instruments’ EXCUWI ELITEpro XC Energy Logger with WiFi Communication and an internal antenna is a primary member of the ELITEpro XC series. Boasting 4 analog input channels, configurable for voltage or current input, the EXCUWI analyzes and stores electrical consumption data. The energy logger monitors current on each phase using direct connections to each phase of the voltage and interchangeable CT options, like RoCoil or split-core CTs. See the accessories tab for available DENT CTs.
Demand data, kWh/kW energy and nearly all related monitoring and diagnostic energy parameters on single or three-phase circuit installations can be captured with the EXCUWI. Even electrical load diagnostic parameters, like power factor (Apparent and Displacement) can be captured.
With the EXCUWI’s specific configuration and supplied ELOG Software, the logger can be accessed from any PC on the network via the WiFi interface. Or, use the EXCUWI as its own WiFi hotspot to observe data in real-time from up to 100 ft away.
