Battery Backup Unit Cabinets (CUBE BBU Series) are pad mount enclosures designed to provide superior environmental protection of battery strings and are ideally suited for cell sites and other outdoor environments where a large amount of battery backup is required. Multiple BBU cabinets can be combined to achieve an even greater amount of battery backup time. BBU cabinets can be installed adjacent to or remotely from other CUBE Macro Cell cabinet solutions (such as CUBE-PM639 Series or CUBE-SS Series models) to form a complete Macro Cell or CRAN Node solution. All three of these cabinet series are built to the same height, width and depth dimensions to provide an aesthetically pleasing lineup that facilitates uniform space requirements. Supports a variety of configuration options including solutions for 12V monoblock and 2V batteries Supports Ni-Cd or VRLA batteries with circuit breaker disconnects for each string Wide range of thermal management options for even the most demanding heat dissipation needs allows for optimization of thermal performance and reduced energy costs Various accessories available including plinths, top hat cable entry compartments, and retractable overhangs Specifically designed for Macro Cell Site and Centralized Radio Access Network (CRAN) applications, provides an economical alternative to shelter and hut deployments Includes bolt-mounted lifting ears for placement by crane or other lifting equipment Optional composite mounting platforms reduce cost and deployment time compared to traditional concrete pad installations
