APC SRT1000XLA - Smart-UPS On-Line 1000VA Tower, 120V

Overview

The APC Smart-UPS On-Line SRT1000XLA provides continuous double-conversion protection in a compact tower form factor. Delivering 1000VA / 900W at 120V, it ensures clean sine wave output for mission-critical servers, storage, and network devices. Designed with scalable runtime and SmartSlot expansion, this UPS combines reliability with flexibility for evolving IT environments.

Key Features & Benefits

• Double Conversion Online: Continuous AC to DC and back to AC power conditioning delivers stable sine wave output.
• 1000VA/900W Capacity: Supports essential IT loads, storage, and networking hardware.
• Outlet Flexibility: Six NEMA 5-15R outlets for versatile equipment support.
• Extendable Runtime: Connects to external battery packs for longer backup during outages.
• USB & SmartSlot: Provides local management and expansion capability for network cards.
• ENERGY STAR® Certified: High efficiency minimizes operating costs and environmental impact.

Technical Deep Dive

The SRT1000XLA leverages double-conversion online topology, where input power is continuously converted to DC and inverted back to AC. This isolates connected loads from power anomalies such as surges, dips, and harmonic distortion, ensuring pure sine wave output suitable for sensitive IT hardware.

Its battery system uses a 48 V lead-acid configuration with a typical recharge time of 3 hours. Extended runtime is possible through additional battery modules. With a 3:1 crest factor and less than 2% harmonic distortion, it handles demanding electronic loads reliably.

The unit includes SmartSlot expansion for management cards, plus USB connectivity for configuration and monitoring. Audible and visual alarms notify users of operational states by severity, and built-in surge suppression (432 J) provides additional protection.

Ideal Applications

• Tower deployments for servers, network devices, and storage
• Small to medium business IT environments requiring scalable runtime
• Distributed IT and edge computing setups
• Healthcare and finance environments demanding zero downtime
