The RP Series 2U is a rack-mount AC-DC switching supply built for small and medium communication and power systems. It converts a 110 or 220Vac mains feed into a regulated 24 / 48 / 110 / 220VDC bus for exchanges, microwave links, digital equipment, optical transmission gear and station DC panels.
Design notes
Each module uses a dual-transistor forward topology with isolation between modules, so a fault stays inside one module. In an N+1 configuration the remaining modules continue to supply the load and share current automatically — a failed unit can be taken out without disturbing the others. The wide input window covers both 110Vac and 220Vac grid standards and the voltage swings common on remote sites, while the -10 to +50 deg C rating keeps full output in unconditioned cabinets. A 3½-digit meter option gives local voltage and current readout.
Configuration
Specify the DC bus voltage, the load current and the N+1 spare count, the AC feed, and whether the meter version is required. The common builds are 4830 / 4850 / 48100 for 48V plants and 11020 / 22010 for 110 / 220V station buses. Where the source is already DC, use the RP DC-DC Converter instead; for a complete 48V embedded system with monitoring and distribution see the RT4860.
