Product boosts and regulates the nominal -48-voltVdc plant voltage commonly provided by an Infinity S or Infinity M power system to -58Vdc. The -58Vdc is provided to an integrated, common system bus structure and is then deployed to loads through pluggable dc breakers, which provide overcurrent protection. The boosted voltage provides greater reach and reduces current flow in cables, which, in turn, decreases heat loss and improves overall system efficiency. Converters can be connected in parallel for larger loads and can be configured with N+1 redundancy, enhancing system reliability and helping to improve remote radio head uptime.
