Batteries[edit]

The section on batteries seems out-of-date; it's all about lead-acid batteries. Sayitclearly (talk) 13:13, 1 December 2017 (UTC)[reply]

Intro seems fine[edit]

Extending it beyond two paragraphs seems like overkill to me. It contains what most people would want to know in brief summary. Actually one of the better intros really.--Weasel tango (talk) 20:24, 20 June 2018 (UTC)[reply]

looking for CPSS or CSS info[edit]

hi

i'm looking in this article, or on other here in wikipedia, info about what i know as "Central Power Supply System" CPSS or "Central Supply Systems" CSS, see www.riello-ups.com/questions/31-what-s-the-difference-between-a-central-power-supply-system-and-a-ups and www.riello-ups.co.uk/products/6-bespoke-solutions/75-css-central-supply-systems

in italian language, this is usually called "soccorritore" (resquer)

maybe CPSS/CSS is not his best know name on english, i don't know.

can someone please point me to a related section/article (if exist), so that i can link it to the new stub-article on the italian wiki about this (:it:Central Power Supply System)?

thank you

I am not sure, I would assume it would be under backup power supply, but that redirects to UPS... I think Continual_power_system or Emergency_power_system would cover it but they are not the same if I look at the Riello links you provided. Rmvandijk (talk) 09:41, 28 February 2020 (UTC)[reply]

Thank you for reply; it is strange that an emergency device regulated by a European standard (EN 50171) has so little literature on the internet; maybe there will be something more in other European languages (French, German ...) than in English. Anyway, here below some links to English content:

What happened to delta conversion?[edit]

I remember reading documents a decade or so ago about APCs delta conversion UPSs, they promised the output quality benefits of online UPSs without the efficiency drawbacks, but they seem to have disappeared both from this page on wikipedia and from the UPS market.

Does anyone know what happened? were their major drawbacks? were the benefits simply smaller than APC anticiated? did the technology just get lost in politics after the merger? Plugwash (talk) 00:22, 29 May 2021 (UTC)[reply]
