3-Phase Power Measurement Modules with Harmonics
WAGO Corporation's 3-Phase Power Measurement Modules (3PMM), part of the new power measurement family, provide energy consumption and power quality analysis in an I/O module form-factor, eliminating stand-alone power measurement equipment. The 12mm wide 750-494 and 24mm 750-495 capture and analyze reactive, apparent and effective power, power factor, phase angle, frequency and over/under voltage. These modules also identify heat-generating harmonic distortions from non-linear loads that can result in machine failure.
WAGO’s 3-Phase Power Measurement Modules are cost-effective measurement devices. Metrics can be transmitted via fieldbus (e.g., BACnet, EtherNet/IP or PROFIBUS) with WAGO’s 750 Series fieldbus independents to higher-level systems for machine protection and energy tracking.
WAGO-I/O-CHECK software simplifies parameterization and energy analysis via a four-quadrant display that shows if a load is inductive or capacitive, and whether it’s producing or consuming. I/O-CHECK also offers an easy-to-view energy dashboard, 3-phase and single phase energy detail, harmonic display to the 41st harmonic and simple configuration.
Beyond measurement, the 750-494 and 750-495 can: Guide preventive maintenance — Pinpoint machinery with increasing energy draws, which often signals a need for maintenance. Support ISO 5001 Energy Management initiatives — Measurement data from 750-494 and 750-495 can be used to collect and analyze energy usage. And Localize disturbances such as voltage spikes.
The 750-494 monitors 480V systems and has an option for operating in harsh environments with temperatures of -20 to +60 degrees C. The 750-495 tracks characteristics for a 480/690V network and has a variant to connect to WAGO Rogowski Coils. Both power measurement modules are compatible with WAGO Current Transformer Blocks.
The 3-Phase Power Measurement Modules join the entry-level 750-493 3PMM and 750-645 2-Channel Vibration and Roller Bearing Monitoring Module (VIB-I/O) in WAGO’s Capital Asset Management portfolio. This I/O supports diverse appliances from mining applications to biotech labs, where it helps protect specimens from power outages.
