eSure™ Rectifier DC Power for Business-Critical Continuity™ R48-2000e eSure™ Rectifier -48 V DC, 2000 W Features and Benefits Optimized depth-reduced footprint allows installation in short-depth racks and cabinets DSP (Digital Signaling Processor)means fewer components, optimized operation and active load sharing for increased reliability Description The eSure™ R48-2000e rectifier converts standard AC supply voltages into stable nominal-48V DC voltage adjustable to the needs of the application. The R482000e 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. Compliant with global standardsdelivers quality, performance and reliability no matter what the application or location demands High efficiency, 96.5%-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 +80°C / 176°F) -meets the harshest climatic environment requirements R48-2000e eSure™ Rectifier R48-2000e Technical Specifications, R48-2000e DC Output Output Voltage, Adjustment Range Output Power Output Power, Derated for Input Voltage Output Current Output Current limit set Point Efficiency Psophometric noise (system) Temperature Derating R 48-2000e Output power vs. Temperature at 290V≥Vin≥176 Vac % of output power 200 to 250 V AC 85 to 300 V AC 45 to 65 Hz 13 A 0.99 <5% from 50 to 100% of rated load 120 100 80 60 40 20 0 -40 -20 0 20 40 60 80 100 Temperature (°C) -42 to -58 V DC 2000W@Vout >48VDC See Diagram 41.7A@-48VDC 0 to 41.7A 96.5% peak <2 mV typical <38 dBrnc typical See diagram R 48-2000e Output power vs. Input voltage and Vo>48V at Temp≤55°C % of output power AC Input Input Voltage, Nominal Input Voltage, Permitted Variation Line Frequency Max Input Current Power Factor THD (Total Harmonic Distortion) 120 100 80 60 40 20 0 0 50 100 150 200 250 300 350 Input voltage (VAC) 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 -40 to +80°C, -40 to +176°F Temperature Range, Storage -40 to +80°C, -40 to +176°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 86× 84.5×272mm / 3.39×3.33×10.71 inches 2.4kg/5.3lbs 60 50 40 30 20 10 0 See separate ACU/ACU+ and SCU/SCU+ datasheets Ordering information Description Rectifier 48V,2000W Product Code 1R482000eXXX 5 10 15 20 25 30 35 40 45 Efficiency Curve 98 96 94 92 90 88 86 84 Other parts Controller Units 0 Output current(A) Efficiency (%) Environmental Temperature Range, Operating R48-2000e Output voltage v.s.
