Vertiv SmartCloset 42U 3,000 VA Line Interactive LI UPS, 120V | Rack Mount

Keep essential systems running with Vertiv SmartCloset, a 42U rack-oriented power platform centered on a 3,000 VA, 2,700 W line-interactive UPS. This model is designed for 120 V environments where consistent power quality and controlled battery backup are required for network closets, branch sites, and edge infrastructure. Line-interactive operation helps correct everyday voltage swings without relying on battery power for every disturbance, which supports better battery preservation and steadier operation. The included networking card gives administrators a path to remote monitoring, making it easier to track UPS status and power events across distributed locations. Automatic voltage regulation is part of the system, and the lead-acid, valve-regulated battery design aligns with enterprise backup power expectations. The 3-year limited warranty adds deployment confidence for teams standardizing on a more complete rack power solution. Compared with basic UPS units, this SmartCloset configuration is built to do more than bridge outages. It combines rack integration, power conditioning, and management visibility in one platform, which is exactly what higher-value infrastructure demands when downtime is not an option.
