APC (network environments)

APC has expanded its Smart-UPS line with the Smart-UPS Rack-Mount (RM) 1400/2200/3000 models with extended run (XL). The 3U-high Smart-UPS RM XL units support the power protection needs of rack-optimised servers.

This additional runtime has been integrated into the models, while saving rack space. The Smart-UPS RM 1400/2200/3000 cost $1,080, $2,145 and $2,629 (inc GST), respectively. They are sold through Anixter, Express Data, Ingram Micro and Tech Pacific.
