Maintain uptime where rack space is tight and power quality matters. The Eaton SMART1500RM2UL delivers 1,500 VA / 1,440 W of lithium-ion backup in a 2U rack form factor, giving infrastructure teams a compact way to protect network gear, edge servers, and storage appliances without giving up valuable rack units. Designed for 110 V, 115 V, and 120 V input environments, this UPS supports a practical mix of four NEMA 5-15R outlets and four NEMA 5-15/20R outlets. That outlet combination makes it easier to connect both standard IT equipment and higher-draw devices from a single protected source. The lithium-ion battery platform is a strong fit for deployments that value reduced maintenance and dependable standby performance. With 7.10 minutes of stand-by time, this model is built to bridge short outages and ride through transfers cleanly. The 2U rack-mountable design fits standard infrastructure cabinets and is well suited to branch offices, telecom closets, and edge deployments where every inch of rack space has a cost. For teams comparing UPS options, this model stands out by pairing dense power delivery with a battery technology choice that supports long-term operational efficiency.
