R48-1000 Rectifier -48VDC, 1000W Features and Benefits Low rectifier/subrack height minimize space needed for power in embedded applications DC Power for Business-Critical Continuity™ Description The R48-1000 rectifier converts standard AC supply voltages into stable nominal -48 VDC voltages adjustable to the needs of the application. The R48-1000 is a constant power rectifier designed with the latest patented switch-mode technology using DSP (Digital Signaling Processor) functionality for efficient operation. For a larger load capacity, rectifiers can be connected in parallel and intelligent control can be added with the help of a separate controller. DSP (Digital Signaling Processor) means fewer components, optimized operation and active load sharing for increased reliability Compliant with global standards delivers quality, performance and reliability no matter what the application or location demands High efficiency, ＞92% efficiency reduces power consumption for lower operating costs Hot pluggable facilitates future extensions Wide input voltage range operates in the most demanding environments where input voltage changes Wide temperature operating range (-40°C / -40°F to +75°C / 167°F) meets the harshest climatic environment requirements R48-1000 R48-1000 DC Power for Business-Critical Continuity™ Technical Specifications, R48-1000 DC Output Output Voltage, Adjustment Range Output Power Output Power, Derated for Input Voltage Output Current Efficiency Psophometric Noise (System) Temperature Derating Control and Monitoring Rectifier Alarm and Signaling Visual Indications R48-1000 Output Power vs. Temperature at 264V ≥ Vin ≥ 176 Vac % of output power 200 to 250 V AC 85 to 300 V AC 45 to 65 Hz 6.8 A 0.99 ≤5% for 50%-100% load 120 100 80 60 40 20 0 -40 -20 0 For R48-1000 -42 to -58 V DC 1000W@Vout >48VDC See Diagram 20.83 A @ -48 VDC ＞92% ≤1mV; ≤32dBrnc See Diagram Environmental Temperature Range, Operating -40 to +75°C, -40 to +167°F Temperature Range, Storage -40 to +75°C, -40 to +167°F Relative Humidity Altitude EMC Safety 0 to 95% 2000 m, 6560 ft at full power ETSI EN 300 386 class B, FCC CFR 47 Part 15 class B, Telcordia GR-1089-CORE class B IEC 60950, EN 60950, UL 60950 Mechanics Dimensions (H×W×D) Weight 40.8×86.5×241mm (1.6×3.4×9.5 inches) 1.25 kg (2.76 lbs) Other parts Controller Units See separate ACU+ and SCU+ datasheets Ordering information Product Name Rectifier R48-1000 www.emersonnetworkpower.com www.emersonnetworkpower.com/energysystems www.DCpowerefficiency.com 40 60 80 100 Temperature (°C) Output Power vs. Input voltage and Vo > 48V at Temp ≥45°C Alarm and status reported via CAN bus to system controller Green LED: Normal Operation Yellow LED: Alarm Red LED: Failure Flashing Red LED: Fan Failure Emerson Network Power.
