IUC-7X-WTX: Isolated Watts Transducer            specsheet 

Features: High Input-Output-Power Isolation (1500VAC Test) Single or Double Element Units for One or Three Phase Systems Industry Standard Outputs: 4-20 mA, 1-5 VDC, more Accurate with Distorted Waveforms Less than 1VA Burden on P.T. and C.T. Standard Calibrations: 500 Watts (-WT1), 1000 Watts (-WT2) Custom Calibrations Available Power: 117 VAC 50/60 Hz (Optional 24 VDC) High Noise Rejection CSA and NRTL Approved (LR 51078)

Function:
The IUC-7X-WT1 is a single element watts transducer to measure the power being consumed by a machine. It measures voltage and current and instantaneously multiplies the two to obtain the power in watts. The instrument is intended for single phase apllications, but can be used in a three phase system.

The IUC-7X-WT2 is a double element watts transducer which operates identically to the -WT1 but has two voltage and current inputs. This yields much greater accuracy for three phase applications than the -WT1.
