Voltage stability without online complexity

Power quality disturbances — voltage fluctuations, over-voltage, under-voltage, and blackouts — occur unexpectedly. When they do, the S71 activates to protect connected critical loads, from a desktop computer to a business telephone system. AVR corrects sags and swells without switching to battery, preserving battery life and maintaining stable output.

Installation is plug-and-play, providing backup power protection right out of the box. The touch LCD offers real-time monitoring of UPS parameters, while bundled shutdown and monitoring software enables UPS and remote device control over the network. This positions the S71 between standby UPS systems and online or lithium platforms — better power stability, while keeping deployment simple and cost-efficient.

What the S71 includes

The enhanced entry tier for distributed power

The S71 serves as the enhanced entry tier within the Xtreme Power distributed UPS architecture, bridging the gap between basic backup and higher-performance platforms.

Distributed UPS architecture comparison

The S71 improves voltage stability compared to standby UPS systems, while the P80 introduces rack-based deployment, pure sine wave output, and scalable runtime for structured IT environments.

Compared to standby platforms, the S71 adds voltage regulation and reduces unnecessary battery transfers. Compared to online UPS systems, it provides a simpler, more efficient, and cost-effective solution where continuous power conditioning is not required.

Replace APC, Eaton, and Vertiv line-interactive UPS

The S71 is commonly deployed as a standardized replacement for line-interactive UPS platforms such as APC Smart-UPS (SMT series), Eaton 5P, and Vertiv Liebert PSI — supporting consistent deployment across distributed environments while adding TAA compliance and stable voltage regulation.

Three models, 700–1500 VA

Capacity guidance: 700 VA for small network devices and desktop equipment; 1000 VA for POS, AV, and distributed IT loads; 1500 VA for higher-load or multi-device environments. The S71-700 uses a removable 6 ft C13-to-5-15P cord (C14 inlet); the 1000 and 1500 use a 6 ft 5-15P cord.

Estimated runtime by load

Runtimes in approximate minutes at the listed VA load. Actual runtime varies with battery age, temperature, and load. A dash indicates a load beyond that model’s rating. Size it with the UPS selector →

Built for home, office, and distributed environments

The tower form factor installs flexibly alongside equipment — on a desk, at a POS station, within an AV setup, or in a small network environment — without requiring rack infrastructure, suiting both new deployments and retrofits.

When to consider lithium UPS platforms

For applications requiring longer lifecycle, reduced maintenance, or improved performance in high-temperature or space-constrained environments, lithium-based platforms may be considered. At the device level the most direct alternative is the J60 Series — longer battery lifespan, faster recharge, compact form factors, and operation at higher ambient temperatures. For rack-based or higher-power needs, lithium platforms such as P91 Li and J90 extend these benefits into structured IT environments.
