About this file

This is a detailed equipment specification document for an Uninterruptible Power Supply (UPS) system as part of a Federal Aviation Administration (FAA) procurement. The specification defines comprehensive performance requirements for single non-redundant, three-phase UPS modules sized from 10 kVA to 550 kVA, with input/output voltages at 208/120 or 480/277 volts. The UPS system must include a static uninterruptible power supply unit, battery system (VRLA, VLA, or Lithium-Ion options), battery monitor, remote monitoring interface, manual maintenance bypass equipment, load bank, and synchronization capability for parallel-redundant configurations. Environmental operating requirements specify ambient temperatures of 0°C to 40°C for the UPS unit and 15°C to 27°C for batteries, with operation up to 3,300 feet without de-rating. Battery backup capacity must support at least 15 minutes of 100% rated load for units up to 150 kVA and 8 minutes for larger units at 80% end-of-life capacity.

The specification mandates rigorous performance standards including 89% minimum AC-to-AC efficiency, ±1% output voltage regulation for balanced loads, maximum 73 dBA acoustical noise, 60,000-hour MTBF reliability, and 6-hour maximum mean time to repair. The UPS must suppress transient voltage conditions, handle inrush currents not exceeding 8 times steady-state rating at 0.01 seconds, support 300% short circuit current for one cycle, and automatically transfer loads between UPS and bypass sources without interruption. Control systems must provide digital logic with self-diagnostic capabilities to the line-replaceable unit level, comprehensive metering and alarm functions through local and remote interfaces (RS232/485, Ethernet), and integration with FAA's Environmental Remote Monitoring System (ERMS) and Modbus protocols. The document includes extensive testing requirements covering factory witness tests, site commissioning, steady-state and transient load testing, battery capacity verification, efficiency measurements, harmonic distortion analysis, and 24-hour burn-in testing, with detailed checklists and baseline data collection procedures to verify compliance with all specified performance parameters.
