The (Power Supply Unit 4813) is a high-performance voltage booster designed to support remote radio systems in telecommunications networks. It primarily functions as a DC-to-DC converter, taking standard -48 V DC input and boosting it to a stable -58 V DC output to maintain power integrity over long cable runs to Radio Remote Units (RRUs).
