• Three-phase Power Output: maximum voltage up to 576 V, maximum current up to 120 A. The minimum current output is as low as 0.2 mA, which is the basis for the starting test of the electric energy meter under test.
• High-order Harmonic Output/Measurement: It can output 2 to 127 harmonics with adjustable amplitude/phase to complete the standard harmonic calibration of the energy meter, or to analyze the harmonic content and harmonic distortion of the tested three-phase source.
