WT3000
Overview
For three-phase power measuring, the WT3000 Precision
Power Analyzer provides a basic power accuracy of
±0.02% of reading. It also offers bandwidth for DC or
0.1 Hz–1 MHz and accepts up to 4 input elements,
facilitating high pre ci sion effi ciency measurements
through simultaneous measurement during I/O of
in vert ers and other items under test.
This, coupled with the ability to perform normal pow er
and harmonic measurements simultaneously, means
that the WT3000 can offer higher accuracy in evaluation
of instruments and higher effi ciency.

Note: Mixing of the 30 A and 2 A input elements is not supported, whether purchasing a new unit or
reworking an existing one. Also, the unit cannot be modified to change the current range.
Adding input modules after initial product delivery will require rework at the factory.
Please choose your models and configurations carefully, and inquire with your sales
representative if you have any questions.
