DC Power for Business-Critical Continuity™ eSure™ Rectifier R48-2000e3 Key Features High efficiency, above 96% – reduces power consumption for lower operating costs Full output power (2kW) up to +65 ° C allows savings on climate system and operating costs High power density – reduced footprint allows installation in short-depth racks and cabinets In addition to reducing power consumption and lowering operating cost, eSure™ high-efficiency rectifiers offer superior performance and uncompromised reliability. Description The 2000W high-efficiency eSure™ rectifier ( model R48-2000e3) is designed to convert standard AC supply voltages into stable nominal -48 V DC voltage that is adjustable to application needs. The R48-2000e3 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. Wide input voltage range to operate in the most demanding environments Hot pluggable – facilitates future expansions and easy maintenance Compliant with global standards – delivers quality, performance and reliability no matter what the application or location demands Efficiency eSure™ Rectifier Efficiency Curve 98% 96% 94% eSure™Rectifier 92% 90% 88% 86% 84% 10% 2013.09 20% 30% 40% 50% 60% 70% 80% 90% 100% Load 1 eSure™ Rectifier R48-2000e3 DC Output Output Voltage, Adjustment Range Output Power Output Power, Derated for Input Voltage 200 to 250 VAC 85 to 300 VAC 45 to 65 Hz 12 A >0.99 for 50%-100% load ≤5% for 50%-100% load at 208Vac, 220Vac, 230Vac, 240Vac 176 85 120 300 100 80 60 40 20 0 0 50 100 150 200 250 Output Power vs. Temperature at Uin > 200VAC See diagram Output Current Limit Set Point Peak Efficiency Temperature Derating 0 to 42 A 96.2% Full output power up to +65°C at input voltage range >200 - 300VAC ( >176 - 200VAC, +55°C) 65 70 120 100 80 60 40 20 0 -40 -20 0 20 40 60 80 100 120 Temperature (°C) Alarm and status reported via CAN bus to system controller Green LED: Normal Operation Yellow LED: Alarm Red LED: Failure Output voltage vs. Output current, max. output power 2000 W 34.5 41.7 -40 to 80°C,-40 to +176°F (See diagram for de-rating) -40 to +70°C, -40 to +158°F 0 to 95% Safety Mechanics Dimensions (H x W x D) Weight 41x84.5x252.5mm/1.61x3.33x9.94 inches 1.13kg/2.49lbs Other Parts Controller Units See separate controller datasheet Output Voltage (V) 60 2000 m, 6560 ft at full power ETSI EN300 386: 2005, Class B.
