Environmental Ratings
•
Operating Ambient Temperature Range:
a)
+55 °C (+131 °F) to +80 °C (+176 °F) with derating output.
b)
-40 °C (-40 °F) to +55 °C (+131 °F) with full power performance.
•
Temperature Coefficient: 0.02% per degrees Celsius.
•
Storage Ambient Temperature Range: -40 °C (-40 °F) to +70 °C (+158 °F).
•
Relative Humidity: This solar converter 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 (4 kV Line to Line, 4 kV Line to Earth). 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 solar converters are fan cooled and utilize front to back forced
ventilation. A solar converter must be mounted so ventilating openings are not blocked and
temperature of the air entering the solar converter does not exceed the Operating Ambient
Temperature Range stated above.
•
Single Solar Converter Audible Noise: At 25 °C ≤50 dB(A) with fan in high speed. Measurement made at
0.6 m distance in front of solar converter and at same horizontal line of the middle of solar converter.
•
High Voltage Category: II
•
Power Distribution System: TN/TT/IT
NOTE!
The solar converter module is recommended to be used in an environment with Pollution of
Degree 2 or less. Pollution Degree 2 applies where there is only non-conductive pollution that might
temporarily become conductive due to occasional condensation (such as the office environment).
