This installation in Borehamwood was to replace an existing UPS in comm’s room. We supplied:

  • Single 20kVA AMM (Multi-Module) UPS
  • No generator on site therefore a long battery back-up was required. However, the space available for the new UPS and batteries was extremely small
  • 12 year design life front access sealed lead acid batteries used to provide 6 hours autonomy at full load. The batteries were housed in a cladded battery stand with a footprint of only 1150x750mm.

Although the battery enclosure weight was 2,650Kgs leg extensions were fitted to the stand
