HiperPFS-3 or -4 for PFC with 115V400Hz nominal?

6 posts / 0 new

Hello,

is it possible to operate HiperPFS-3 or HiperPFS-4 with 115V 400Hz nominal?
PiXi Designer does not "prevent" using 400Hz, but it warns, that the frequency is "outside the standard range".
Are there any suggestions or experiences?

Hi Roland,

Good day. May we know what application are you targeting for such line frequency? Thank you very much.

Hello Leo,

and happy New Year :)

It is a test system to be used at standard AC systems as well as used for diagnostic purposes in an aircraft. The aircraft supply is typically 115V 400Hz AC. The test system is intended to be used "on ground" (no dedicated flight profile foreseen) but directly operated at aircraft supply.
And in order to prevent coupling issues with other aircraft systems, the test system needs to be power factor corrected (also on aircraft supply, as well).

Best regards

Hi Roland,

Good day. Upon further discussion and verification in our side, I would say using 400Hz input line frequency is alright. This shouldn't have any foreseen issue in the overall operation. Hope this helps.

Hello LeoDavinci,
sorry for the delay...
you mentioned that you verified on your side: can you give some information how you verified?
Thanks in advance for a response.

Hi Roland,

There was an internal discussion about the 400Hz application and we confirm that this is ok.
