APC Smart-UPS Ultra On-Line Lithium Ion 10kVA/10kW – 4U Rack/Tower, 230V

Lead-acid batteries in a UPS are heavy, they need a cool room, and they start losing capacity the day you unbox them. If your rack's already tight on space and your cooling budget is already stretched, swapping to lithium ion is the move.

This APC Smart-UPS Ultra On-Line packs 10 kVA / 10 kW of on-line pure sine wave power into a 4U chassis — half the vertical footprint of the 7U three-phase units. It runs off a standard 230 V single-phase supply, so no three-phase feed required. Rack it or stand it on the floor; both work.

Lithium-ion chemistry means less weight in your rack, no electrolyte to manage, and a longer usable life before you're back on the replacement treadmill. If your current UPS is a 4U lead-acid unit that's been throwing capacity warnings, this is the direct upgrade path without re-cabling the room.

230 V input, 230 V output. 4U. Lithium ion. That's the spec. The rest is uptime you don't have to think about until it matters
