Side-by-side comparison of features, pricing, ratings, and alternatives.
The Emerson Liebert NX is an advanced double-conversion online uninterruptible power supply designed to deliver clean, continuous power to data centers, industrial processes, and telecommunications networks. It features a transformer-free design that maximizes energy efficiency while maintaining a compact footprint. Equipped with intelligent monitoring capabilities and robust fault tolerance, the Liebert NX protects sensitive equipment from voltage fluctuations, surges, and complete power outages. Its modular architecture and intuitive control interface make it a reliable choice for enterprise environments requiring high uptime.
The APC Back-UPS Pro 1500VA provides battery backup and surge protection for home office equipment, networking gear, and gaming PCs, automatically switching to battery power within milliseconds of an outage to prevent data loss and hardware damage. Its LCD display shows real-time battery status, load level, and estimated runtime, while the companion PowerChute software can automatically save open files and safely shut down a connected computer during extended outages. Color-coded outlets distinguish battery-backed sockets from surge-only sockets, making it easy to prioritize which devices stay powered longest during an outage.
Around $200 MSRP.
