Environmental Ratings
Operating Ambient Temperature Range:
a) -40°C (-40°F) to +75°C (+167°F) with derating output.
b) -40°C (-40°F) to +45 C (+113 F) with full power performance.
c) Temperature Coefficient:
0.01% per degrees Celsius.
Storage Ambient Temperature Range: -40°C (-40°F) to 75°C (+167°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 Installation Class 4, and capable
of withstanding surges per ANSI/IEEE C 62.41 1999 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) At 25°C ≤ 53dB(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.
b) At 25°C ≤ 45dB(A) with fan in low speed; Measurement made at 1m distance
in front of Rectifier and at same horizontal line of the middle of Rectifier.
EMI/RFI Suppression:
a) Rectifiers operating in an approved Rectifier Mounting Shelf conform to the
requirements of FCC rules Part 15, Subpart B, Class B for Radiated and
Conducted emissions limits.
b) Rectifiers operating in an approved Rectifier Mounting Shelf conform to the
requirements of European Norm, EN55022, Class B for Radiated and Conducted
emissions limits.
Compliance Information:
a) Safety Compliance: This unit meets the requirements of UL 60950-1, Standard
for Information Technology Equipment, and is UL Recognized as a power supply
for use in Telephone, Electronic Data Processing or Information Processing
Equipment. This unit meets the requirements of CAN/CSA 22.2, No. 60950-00
and is tested and Certified by UL ("c UR")as a Component Type Power Supply.
b) The Rectifiers are RoHS compliant, 5/6.
