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.
