Does Kronos use Active or Passive PFC in its power supply?

[evimidiman]

Hi,

Since the Kronos streams from the SSD whenever you play its pianos, I would think buying an Uninterruptible Power Supply (UPS) would be crucial to the stability of using this instrument long-term to avoid brownouts, sags, etc.

Does anybody know if the Kronos uses Active or Passive PFC in its power supply?

That makes a difference on what type of UPS to use.

Thanks in advance,

I don't know the answer to your question but would you be able to figure it out with a detailed picture of the inside of the power supply?

It's also crucial to avoid the 2 minute boot time on stage if the power glithed such that it crashes the Kronos, your band mates are carrying on and you look like a lemon!

I wish I was smart enough to be able to look at and know what type of circuit it is, but I'm not Perhaps somebody at Korg can tell us, because Active or Passive PFC (Power Factor Conversion) is important since Active REQUIRES an UPS that can deliver a pure sine wave. Older and cheaper UPS's cannot do that and they can also damage any unit that is plugged into it when it delivers backup power.

So true!!! I should have mentioned that I have the newest Kronos 2, 61 key, so I don't know if they have had different power supplies in the 3 versions of Kronos hardware...
