VA and watts are two ratings, and the smaller one is the real one · review

Legrand KEOR PDU, 800 VA / 480 W, 19-inch rack, 2U review

A combined rack power distribution unit and UPS occupying two rack units, rated 800 VA and 480 W, with eight outlets and up to fifteen minutes of bridging time.

By Jean-Benoit Buisson

The bottom line A sensible two-in-one for a small rack, publishing a bridging time and an outlet count. It gives no transfer time, no load for its fifteen minutes, and names its software only by the operating systems it runs on.

A rack distribution unit with a UPS inside it, in two units of height.

The argument

A small rack has limited height and a limited budget for chassis. Combining distribution and backup into one 2U unit removes a separate box, its cables and its rails. That is the whole design and it is a good one.

What is published

800 VA, 480 W, eight Schuko CEE7/3 outlets backed on mains failure, up to fifteen minutes of bridging, three status LEDs, and compatibility with a Linux or Windows PC.

What fifteen minutes means

A maximum, with no load stated. At a light load it is plausible; at 480 W it will be a fraction of that. Every runtime figure in this catalogue has the same problem, and this one is a maximum rather than a typical value.

The figure a rack actually turns on

Transfer time. Equipment in a rack — switches, servers, storage — has varying tolerance for an interruption, and none of it is knowable without the number. It is not published.

Availability

German, French, Italian and Spanish Amazon stores quoted 213 € to 290 € when this page was compiled.

American and British Amazon stores carry it too, priced in their own currency, which the euro range above deliberately omits.

What it gets right, and what it leaves out

Strengths

Two functions in two rack units — distribution and backup in one chassis
A maximum bridging time is published, which four of six here omit
Three status LEDs for monitoring without software

Compromises

No transfer time, which is the figure a rack of equipment turns on
The software is described by operating system rather than named
A maximum bridging time without a load, so it describes a best case

Questions owners ask about this one

What is a PDU doing with a UPS inside it?

Saving rack space. A distribution unit spreads one feed across eight outlets; a UPS holds those outlets up when the feed fails. Combining them in two rack units removes a separate chassis, which in a small rack is the whole argument.

Is fifteen minutes useful?

It depends entirely on the load, which the listing does not state. Fifteen minutes is a maximum — at a light load. For a rack drawing near 480 W it will be considerably less, and the figure alone cannot be planned against.
