U.S. DOE Proposes UPS Efficiency Standard

[William Gaatjes]

Often i get email from various semiconductor Manufacturers.
This caught my eye :
Well, i could write it down but is already below.

The U.S. Department of Energy (DOE) has published a Notice of Proposed Rulemaking (NOPR) describing minimum efficiency levels for uninterruptible power supplies (UPSs). The proposal is an offshoot of the DOE’s battery charger efficiency standard. The UPS standard is expected to save consumers as much as $4.4 billion in energy savings for products purchased between 2019 and 2048.

If adopted, the efficiency requirements would apply to the UPS product classes listed in in the table below. The standard will affect UPS products manufactured in, or imported into, the United States, starting two years after publication in the Federal Register.

The proposed requirements are expressed in average load-adjusted efficiency and are based on a UPS’s rated output power (Prated) as shown below.

Details and a document are here :

What does this mean in practice ? How much of an efficiency increase can we expect when comparing the average ups ?

From what I recall, this had to do with charging, and it added cost to a UPS that the OEMs didn't exactly like.
I'll try to find the site I read this on, and come back and post a link.
