New and Original Emerson Rectifier telecom Module R48-3500E Product Description Working Temperature -40°C~70°C output power 3500W input voltage range 85Vac~300Vac rated input voltage 200Vac~250Vac incoming current <,20A Rated input network frequency 50Hz/60Hz Output dc voltage range 42V~58V Output dc current 0A~65.5A The eSure™ R48-3500e high-efficiency rectifier is designed to convert standard AC supply voltages into stable nominal -48V DC voltage that is adjustable to application needs. The R48-3500e is a constant power rectifier designed with the latest patented switchmode technology, using DSP (Digital Signaling Processor) functionality for efficient operation. For a higher load capacity, rectifiers can be connected in parallel, and intelligent control can be added with the help of a separate controller. Features 1.3500 Watt high-efficiency rectifier designed for -48V DC power applications. 2. Optimized depth – reduced footprint allows installation in short-depth racks and cabinets. 3. DSP (Digital Signaling Processor) – means fewer components. optimized operation and active load sharing for increased reliability. 4. Compliant with global standards – delivers quality, performance and reliability no matter what the application or location demands. 5. High efficiency, approaching 97% – reduces power consumption for lower operating costs. 6. Hot pluggable – facilitates future extensions. * Emerson's high-efficiency rectifier module R48-3500e adopts non-destructive hot-swapping technology, and its output and input have soft-start units, so the output voltage of the system will not fluctuate when the module is swapped. * working temperature: -40°C~70°C * altitude: less than 2000m (2000m with upper power). * output power: 3500W (input voltage 176Vac~30Vac). * input voltage range: 85Vac~300Vac (single phase three wire system). * rated input voltage: 200Vac~250Vac * maximum static voltage without working time: 415Vac * input current: <,20A @2900W/176Vac * starting current: <,32A * rated input frequency: 50Hz/60Hz * output DC voltage range: 42V~58V * output DC current: 0A~65.5A * regulation accuracy: less than or equal to 0.5%. * load adjustment rate: less than or equal to 0.5% * voltage adjustment rate: less than or equal to 0.1%. * power factor: greater than or equal to 0.90 (@25%~50% rated output power).
