Written by GovTribe AI ·

This document is a technical specification for replacing batteries in a static uninterruptible power supply (UPS) system at a Department of Veterans Affairs medical facility. Key details include:

  • The specification covers furnishing and installing replacement batteries for an existing //kVA, //kW, //non// //N+1// redundant UPS system to provide a discharge time of 15 to 240 minutes at 25 degrees Celsius. The new batteries must be capable of delivering 125 percent of the UPS's full rated output load.

  • Technical requirements include specifications for the battery type, construction, cabinet, cables, and disconnect switch. Load, voltage transient response, and overcurrent protection tests are to be performed, along with a 24-hour continuous load test at varying levels, a full load battery discharge test, and a complete battery discharge and recharge test while recording instrument readings.

  • The related federal contract opportunity is solicitation number 36C24924Q0048 for replacing the UPS batteries at Department of Veterans Affairs medical center location 626-24-1-4123-0173.
