The product range offers products that are rack-based and can fit any standard 19 rack. The design of the product is similar to that of other APC products, so you are guaranteed to have the best look and feel. They are only 2U in height and deliver up to 4.5kW to your load. (Note: 1U is equal to 1.75) They are reduced from 208V straight down to 120 V to distribute to the load. They are designed to work with APC Symmetra and Smart-UPS 208V products.
