Features and Benefits

eSure™ Rectifier 
-48 V DC, 2000 W

• 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
• Compliant with global standards-delivers 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

The rectifier delivers full power when operating at an ambient temperature of +45°C (+113°F) or below (1R482000 and 1R2000H) or +55°C (+131°F) or below (1R482000e). Each rectifier continuously monitors the ambient temperature surrounding the power conversion circuit. If this temperature for any reason (such as a high ambient temperature or failed fan) increases above approximately +45°C (+113°F) (R48-2000 and R48-2000H) or +55°C (+131°F) (R48-2000e), the rectifier will not shut down. Rather, the rectifier limits its maximum output power to maintain the temperature of the power conversion circuit within design parameters. Operation between +45°C (+113°F) (R48-2000 and R48-2000H) or +55°C (+131°F) (R48-2000e) and +80°C (+176°F) will result in output power being decreased. Full power capability is restored when the temperature decreases to below approximately +45°C (+113°F) (R48-2000 and R48-2000H) or +55°C (+131°F) (R48-2000e).
