back to article Cloudy with a chance of colocation: Taiwan's Delta Electronics rolls out beastly 600kVA UPS

Taiwanese power distribution and thermal management specialist Delta Electronics has introduced a mammoth of a UPS system designed for the needs of the largest of bit barns. The latest box in the Ultron DPS range [isn't that a copyright violation? – Ed] can provide up to 600kVA of apparent power – and a maximum of eight …

    A megawatt in a single rack?

    Hope that rack is kept well away from racks containing servers and storage, because if there's a bad cell in there and it goes up in flames there will be a LOT of flames!

    A bit scary

    "can be equipped with lithium ion batteries"

    I'm surprised that's not Lithium Iron Phosphate. There are earthquakes here and I'd be uncomfortable around flammable LiPo or heavy lead-acid at megawatt scales. 600kVA is in the same ballpark as the momentary peak output of a Tesla S battery pack. Hopefully this thing lives in its own room.

    Delta has owner's manuals online if you're wondering how such beasts are used.

    A pf. of 1 !!!

    I call BS to the 'unity power factor' There will be losses in the system so a pf1 is not likely. High .90's maybe but not 1

      Re: A pf. of 1 !!!

      It's likely that they're creating a sine wave output directly from half-bridges generating high frequency, high voltage PWM into an LC filter. This circuit is virtually lossless except for minor switching losses and, of course, severe overload conditions. The power flow is bi-directional so it can operate as both a source and sink of power. As a result, it doesn't matter what the load power factor is as long as the peak current doesn't overload anything.

      Less sophisticated 3-step "modified sine" outputs are sensitive to the load factor because they're not a sine wave, there's no LC filter to store power, and the middle step is a 0-volt short. They often indicate a bad power factor by exploding.

    600 KVA --- 600,000 Watts is NOT that much power! TWO of the petrol engines from a GMC 1500 Sierra Denali lorry IS MORE THAN that!

    When you get to the level of our Multi-Gigawatt GE Gas Turbines THEN come talk to me!

      Getting such a low output from a 5.3l engine is pitiful. The ratio power/displacement is half the one of the ecoboost engines for instance.

        Yeah it's shit compared to highly strung European engines getting the same power (or more) from a much smaller engine. But an unstrained high-displacement engine is likely to last a lot longer.

      It's a fair sentiment. My car engine can - on paper - pump out ~430kW. Bit of an apples/oranges comparison though. What's the peak energy i.e. how long can 600kW be sustained vs. the Denali's 5.3L engine or my LSX's 6.2L? Which is more likely to nuke itself at sustained high output?

    Well there's Marvel comics and then there's...

    Well, when I was at school, I learnt that Watts = Volts x Amps. So "when every kVA equals 1kW" doesn't seem like an overly impressive claim to make.

    Perhaps it would have sounded more impressive in Standard Reg Units?

    For the BIG LASERS.

    Supposedly this is the backup power supply for all those huge lasers pointed at the sky, and across the Strait in case the mainland hordes decide to attack.

    Either that, or Taiwan has finally found a way to make a miniature power-producing Tokamak.

    Probably both.
