The Delta CPC 3000B-57 is a 48V boost converter designed to match the power needs of remote radio units (RRUs). It raises a 38–58 VDC battery bus to a stable 57–59 VDC (58 VDC default), so the radio receives sufficient voltage without an extra tower-top converter. It delivers up to 3245 W and 55 A at a peak efficiency of 98%, and its modular format slots into the standard shelves of existing DC power systems to create a multi-voltage power solution.
