It needs a few hundred watts of clean backup that fits whichever way the closet actually allows. The Vertiv Liebert PSI5-1100RT120 is a 2U line-interactive unit that bolts into a rack or stands upright as a tower, with the support stands supplied.

Output is pure sine wave rather than a stepped approximation, which is what sensitive power supplies expect. All six NEMA 5-15R receptacles sit on battery and surge protection, fed from a standard NEMA 5-15 input, and the battery is hot-swappable with a four-hour typical recharge, so a cell change does not mean dropping the load. Physically it takes 2U of rack or stands on the included tower feet, and an LCD plus an RJ-45 port cover local status and network connection.\u003c\/p\u003e\n\u003ch3\u003eHighlights\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e1100 VA and 990 W of pure sine wave output:\u003c\/strong\u003e line-interactive protection sized for servers, switches, storage and point-of-sale gear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAVR across a 75 to 146 V input range:\u003c\/strong\u003e corrects sags and swells without discharging the battery, with a 6 ms transfer time when it must switch.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSix NEMA 5-15R outlets:\u003c\/strong\u003e every one of them on both battery and surge protection.\u003c\/li\u003e\n\u003cli\u003eHot-swappable battery with a four-hour typical recharge, giving 10 minutes at half load and 2 minutes at full load.\u003c\/li\u003e\n\u003cli\u003eMounts in 2U of rack or stands as a tower on the supplied feet, shipping with a USB cable and quick start guide and backed by a two-year limited warranty.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Vertiv","offers":[{"title":"Default Title","offer_id":52336370647224,"sku":"PSI5-1100RT120","price":807.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/9110\/4952\/files\/1048722726_c0284ce1-3b35-4098-81aa-5396c358dc42.jpg?v=1764407332","url":"https:\/\/islandelectricalsupply.com\/products\/vertiv-liebert-psi5-1100rt120-ups-1100va-rack-tower","provider":"Island Electrical Supply","version":"1.0","type":"link"}
