The RP Series 2U DC-DC converter is built for communication and power systems that already run on a DC bus but need a second voltage. It converts between 24 / 48 / 110 / 220VDC — for example turning a 110 or 220VDC station battery into a 48VDC telecom rail — without an AC intermediate stage.
Design notes
Dual-transistor forward switching with isolation between modules keeps a fault inside a single module. In N+1 configurations the remaining modules continue to supply the load and share current automatically. The wide input window tolerates the voltage swings of station battery buses, and full rated output is maintained from -10 to +50 deg C. The 19-inch 2U chassis suits standard telecom and power cabinets, and a 3½-digit meter option shows output voltage and current locally.
Configuration
Specify the source DC bus and its fluctuation range, the required output voltage and current, the isolation requirement, the number of modules for N+1 redundancy and the available cabinet height. Common builds are DC110-48V30A-2U and DC220-48V30A-2U. Where the source is AC mains, use the RP 2U AC-DC instead.
