Deliver dependable backup power without giving up rack density. The Middle Atlantic Select Series UPS-S1000R provides 1,000 VA and 600 W in a 1RU rack-mountable design, making it a practical fit for smaller AV and security installations that still need stable power protection. Automatic voltage regulation helps smooth common utility fluctuations, while EMI/RFI noise filtering supports cleaner operation for sensitive electronics. Built for 120 V AC systems with a 90 V AC to 140 V AC input range, this UPS is sized for essential loads that must stay online long enough to bridge brief outages or complete a controlled shutdown. It delivers 3 minutes of runtime at full load and 13 minutes at half load, giving integrators a clear, predictable window for continuity. The compact 1RU footprint is especially valuable in crowded racks where every unit of space matters, and the 3-year limited warranty supports long-term deployment planning. For control processors, networked AV gear, and security components that need protection from power anomalies without overcommitting rack space or budget, the UPS-S1000R offers a focused, professional-grade answer.
