Remarks
(1) Regarding the harmonic output, measurement of harmonics cannot be performed unless the fundamental wave content is 75% or more of the rated voltage.
(2)
An analog output of approximately 100% or more may be output for a few seconds immediately after turning on the auxiliary power supply (until the internal voltage stabilizes).
