Usage of a modified sine wave UPS which has a PFC PSU will not bring about physical damage to both the UPS or even the PSU, just likely failure from the UPS to keep the products powered on when it is actually purported to. **(see caveat underneath)

– Random832 Commented Could nine, 2015 at 17:32 See this Take note by APC on PFC (power element corrected) Laptop or computer power materials, 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 may possibly experience approximately 8ms transfer time; extensive adequate to get rid of power with the PFC power supply, resulting in a momentary inrush because of the PFC, resulting in a potential Overload problem or dropped load by UPS.

Also, as described, the kind of sine wave applied, pure or simulated, could possibly undoubtedly be considered a factor in picking out some units around others Primarily using a high end power supply like yours. Prior investigations and discussions Along with the Seasonic rep, along with a few threads more than on JonnyGuru, have led me to feel that these Seasonic Primary models are delicate to, and do not like, simulated sine wave units and that it's really proposed that only pure sine wave UPS units be applied Using these power supplies if you don't need them to simply shut down after they detect the simulated wave, earning them useless.

The expense of a UPS pales in comparison to the price of changing an entire Laptop or computer, match console, or A different pricey or fragile device.

Surge strips or surge defense crafted into products may very well be a problem to get a UPS which is not at the least near to becoming pure sine wave. Since I required backup power for each Laptop or computer, Television, protection cameras, etcetera. all in the exact same space it had been extra an issue of security which i compensated more for the pure sine wave device. I do not want to worry if some thing might overheat.

Even so, it'd trigger damage in more elaborate equipment that operate right off AC power and count at stake voltage, such as:

They consist of guide and acid, Nonetheless they utilize a sealed guide-acid style, and Unless of course you're taking a drill or perhaps a handsaw towards the battery case, They may be Risk-free to manage.
