This three-phase course of action cuts down AC-side sounds significantly,⁵ so it is possible there are devices which have been developed with the belief that the ensuing sound and ripple over the output of such a supply is relatively clean up, and would get annoyed via the hundreds-of-Hz hash coming out of the modified-sine UPS.

Can you enable?
– Random832 Commented May perhaps nine, 2015 at seventeen:32 See this Notice by APC on PFC (power component corrected) computer power supplies, approximated sine wave UPSs, and UPS overload shutdown: apc.com/us/en/faqs/FA158939 To summarise: UPS switching from utility power to battery power and back again might working experience approximately 8ms transfer time; very long sufficient to get rid of power through the PFC power supply, leading to a momentary inrush by the PFC, leading to a potential Overload situation or dropped load by UPS.
