FLUX are inrush current higher than other types of transformers because of using the gapless core
    and that Z-8H (ultrahigh-μ). That's all the proof that FLUX are high-efficient transformers.

 In case of challenge to magnitude of inrush current when designing the transformer, we can
    respond to it. However, it get less of compact lightweight advantage.

 Measure inrush current by on-off operation of the power-on switch.

 You can know the maximum inrush current at the rate of 1 time per about 20 times, so you will
    reach certainty about the maximum inrush current by on-off operation of 100 times.
