Measure Watts/VARS/Watt(VAR)-Hours (5-500Hz) with MODBUS communication in a DIN-Rail package
Measure simple to complex waveforms over a wide frequency range – all with Z540 or ISO 17025 certification. In addition to OSI's certification capabilities, the Wxx (with MODBUS) offers high accuracy, 5-500Hz frequency range, and analog or MODBUS communication outputs all within the Wxx's DIN-Rail package.

The Wxx line of transducers comes with many variations which allow you to choose the capability needed for your specific application.

You may select: 
•Watts, Watts and VARs, Watts/VARs and Watt-Hours/VAR-Hours
•Over multiple Frequency Ranges

50-60 Hz for simple loads
5-500 Hz (excellent for VSI drives) and other, more-complex loads
Up to the 40th harmonic to ensure DoE Energy Star compliance

•Voltage up to 400VL-N/ 693VL-L (with accuracy) 
•Accuracies from 0.5% of full scale to 0.2% of reading 
•Analog and pulse outputs

•MODBUS communication
