Hi guys,

I consider purchasing a rackmount UPS (SMT1500RMJ2U - same as the model in the title but for the Japanese market, e.g. 100V).
Does anybody know how loud the fans of these units are when they are NOT running on battery power? APC states a value of 46db(A) on their website which would make them rather loud in my opinion.
It would be fine if those numbers are the noise level when the unit is running on battery power but probably a bit too high if it's 24/7.

Thanks in advance for your input.

I have in my homelab two SMT2200RM2U's - rated by APC at 55.0 dBA. They're literally silent when on mains, and get noticeably louder when on battery.
That sounds promising. SMT1500s are regularly available on local auction sites from 80 USD used to <300 USD brand new, w/ LAN card and rails and inclusive of shipping costs. I might give it a try.
