Description
The Vertiv Liebert PSI5-1500RT120TAA is a high-performance, line-interactive uninterruptible power supply designed to protect critical IT and network equipment in government and regulated environments. With 1500VA / 1350W capacity, a 0.9 output power factor, and pure sine wave output on battery, this UPS delivers clean, reliable power to servers, networking gear, storage, and communications systems.
Built for flexibility, the PSI5 supports 2U rack or tower deployment, includes a rotatable LCD display, and features programmable outlet groups that allow load shedding and remote power cycling to extend runtime for critical devices. Advanced Automatic Voltage Regulation (AVR) corrects voltage fluctuations without switching to battery, helping extend battery life and reduce wear.
This TAA-compliant model is ideal for federal, defense, and government IT installations requiring compliance without compromising performance. Support for external battery cabinets enables extended runtime for longer outages, while USB communication allows integration with power management software for safe, orderly shutdowns.
