APC SRT1500XLA Online UPS 1500VA 120V

Overview :

The APC SRT1500XLA is a double-conversion online uninterruptible power supply designed to maintain continuous AC power for critical IT and network equipment. It is commonly deployed by infrastructure engineers and data center operators to protect servers, storage systems, networking hardware, and industrial controllers from power disturbances such as voltage fluctuations, outages, and electrical noise. The online topology ensures zero transfer time during power events, maintaining uninterrupted operation for sensitive loads.

This UPS provides a rated output capacity of 1500VA / 1350W and delivers a pure sine wave output suitable for modern power supplies found in servers, switches, and telecom equipment. It operates with a nominal input and output voltage of 120V AC and supports a wide input voltage range of 108–150V. The unit includes six NEMA 5-15R battery-backed outlets and uses a NEMA 5-15P input connection for standard single-phase circuits.

Within infrastructure environments, the SRT1500XLA is commonly installed in branch IT cabinets, edge network racks, or small server room deployments where high-quality power conditioning is required. The unit is tower-based but can be converted to rack installation using compatible rail kits, allowing deployment within standard 19-inch equipment racks.

Operational integration includes management and monitoring through USB, serial (RJ-45), and SmartSlot expansion for optional network management cards. These interfaces allow integration with centralized power monitoring systems and automated shutdown tools, enabling coordinated power management across connected servers and network devices.

In practical deployments, the SRT1500XLA is often installed in a network rack supporting a small virtualization host, storage appliance, and core switch stack. During a utility outage, the UPS maintains stable sine-wave output while initiating automated shutdown sequences through management software if extended outages occur.

This model should not be used in high-density racks with loads exceeding the 1350W output rating or in environments requiring 208V/230V distribution systems. It is designed for single-phase 120V power ecosystems rather than high-capacity data center power architectures.
