Efficiency Curve [R48-2000H (1R482000H)]

Environmental Ratings:

• Operating Ambient Temperature Range:
a) -40°C (-40°F) to +80°C (+176°F) with derating output.
b) 1R482000 and 1R2000H: -40°C (-40°F) to +45°C (+113°F) with full power performance.
c) 1R482000e: -40°C (-40°F) to +55°C (+131°F) with full power performance.
d) Temperature Coefficient: 0.01% per degrees Celsius.
• Storage Ambient Temperature Range: -40°C (-40°F) to +80°C (+176°F).
• Relative Humidity: This rectifier is capable of operating in an ambient relative humidity range of 0% to
95%, non-condensing.
• Altitude: 2000 m (6560 ft) at full power (power limited for heights above 2000 m).
• Surge Protection: Compliance with EN61000-4-5 (2kV Line to Line, 2kV Line to Earth). Capable of
withstanding surges per ANSI/IEEE C 62.41 1980 Category B3 across the input terminals.
NOTE! This level of protection is a widely used standard for telecommunications power equipment. As
with all such equipment, it is the end user's responsibility to provide an adequately sized Surge
Suppression Device at the commercial power service entrance of the building that reduces all incoming
surges to levels below the classes/categories stated for the equipment.
• Ventilation Requirements: The rectifiers are fan cooled and utilize front to back forced ventilation. A
rectifier must be mounted so ventilating openings are not blocked and temperature of the air entering
the rectifier does not exceed the Operating Ambient Temperature Range stated above.
• Single Rectifier Audible Noise:
a) R48-2000e: At 25°C ≤ 50dB(A) with fan in high speed. Measurement made at 0.6m distance in
front of rectifier and at same horizontal line of the middle of rectifier.
