APC online/double conversion UPS SURT2000XLI -switching frequency?

[Anonymous user]

Greetings...

I've got a european voltage model SURT2000XLI Smart UPS Online and was thinking about using it for audio applications and for audio recording, perhaps with very sensitive microphones, some of which are sensitive to over 100kHz. I know we can't hear such high frequencies, but noise at that range would be better off being filtered out than left to assume it's benign and have a chance of affecting my recordings.

Anyway, I don't wish to start an arguement about audio filters, human hearing range DBT and all that, but would just like to ask what the switching frequency of my particular model of UPS is. Hope this isn't sensitive information.

I'll see what I can find out and report back.

Switching frequency is 23kHz.

*EDIT* - I mistakenly reported 23Hz originally but I meant 23kHz. I just updated it.
