UPS FUJITSU PY LI 1.5 kVA / 1.2 kW rack/tower 2U

The FUJITSU PY LI 1.5 kVA / 1.2 kW rack/tower 2U is a line‑interactive uninterruptible power supply designed to deliver short‑term backup power and voltage regulation for small IT installations. Packaged in a compact 2U chassis that supports both rackmount and tower placement, this UPS maintains power to servers, network devices and workstations during outages, brownouts and voltage spikes. The built‑in AVR (automatic voltage regulation) reduces the need to draw battery power for minor input fluctuations, extending battery life and improving overall system availability.

Advantages

The FUJITSU PY LI combines compact dimensions with a rated output of 1.5 kVA / 1.2 kW, offering a balance between power capacity and space efficiency for small racks and office environments. Line‑interactive topology with AVR ensures stable output voltage under common mains disturbances while conserving battery runtime for genuine outages. The 2U form factor supports straightforward installation in standard 19" racks or standalone tower placement, simplifying deployment in constrained spaces. Its straightforward functionality focuses on core protection features required for small servers, NAS units, switches and workstations.

Suitable for

• Small server rooms and network closets
• Office racks with compact IT equipment
• Workstations and desktop PCs requiring clean shutdown capability
• Network switches, routers and small storage arrays

Key specifications

• Topology: Line‑interactive with automatic voltage regulation (AVR)
• Apparent power: 1.5 kVA
• Active power: 1.2 kW
• Form factor: 2U for rackmount or tower use
• Output waveform: Simulated sine wave (typical for line‑interactive units)
• Output connections: Multiple IEC outlets (model dependent)
• Typical functions: Short‑term battery backup, surge protection and voltage regulation
• Intended environment: Small data closets, office racks and edge IT installations

How to use

Install the UPS in a standard 19" rack using the included mounting kit or place it vertically as a tower on a stable surface. Connect critical equipment to the battery‑backed outlets and non‑critical loads to any surge‑only outlets if present. Ensure the unit is connected to a properly grounded mains outlet and allow the internal battery to fully charge before relying on battery runtime. Monitor the UPS status indicators to confirm normal operation and schedule periodic battery tests and replacements according to the manufacturer’s maintenance guidance.

Usage recommendations

Place the UPS in a ventilated area away from direct heat sources and moisture. Keep the total load below the rated active power (1.2 kW) to ensure reliable backup time; distribute connected devices across outlets to avoid overloading. For servers and storage, configure automatic shutdown software where supported to ensure orderly poweroff during extended outages.
