Portable Power Data Logger – Three Phase Electricity Consumption Monitor
A high-accuracy portable three-phase power and energy data logger designed for temporary electricity monitoring, load profiling, and energy audits. Supports Rogowski coils or 333mV CTs, features RS485 Modbus communication, and delivers Class 0.5 accuracy for professional industrial applications.
This portable power data logger is engineered for short-term and mobile electrical monitoring across industrial, commercial, telecommunications, and utility environments. It supports both three-phase and single-phase systems, enabling flexible deployment for load studies, diagnostics, and energy analysis.
Designed for field technicians and energy auditors, the unit provides real-time measurement of:
-
Voltage
-
Current
-
Active, reactive and apparent power
-
Energy consumption
-
Frequency
-
Harmonics (up to 52nd order)
Current measurement is achieved via Rogowski coils (BNC input) or 333mV CT sensors, allowing safe installation without disconnecting live conductors. This makes it suitable for high-current systems up to 6000A.
A bright 3.5-inch TFT digital display provides clear on-site readings, while the integrated RS485 Modbus-RTU communication enables connection to PLCs, SCADA systems, BMS platforms, or external data logging software for reporting and analysis.
Powered by AA batteries for mobile use or USB Type-C for extended operation, the device is purpose-built for temporary deployment and field diagnostics.
