Typical Input Data: When equipped with one DC-DC converter module.
a)
The output voltage of the DC-DC converter module is initially adjusted to 48 volts at 50% load and
24 volts DC input.
b)
Maximum Current: Input current is 83.32 amperes at full load (31.25 amperes) and 21 volts DC input.

Environmental Ratings
•
Specification Compliant Temperature Range: -20°C to +65°C (-4°F to +149°F).
•
Reduced Load Temperature Range: +50°C to +80°C (+122°F to +176°F).
•
Deviation to Noise Specs. Temperature Range: -40°C to -20°C (-40°F to -4°F).
•
Storage Ambient Temperature Range: -40°C to +85°C (-40°F to +185°F).
•
Humidity: This converter module is capable of operating in an ambient relative humidity range of 0 to
95%, non-condensing.
•
Altitude: The maximum operating ambient temperature should be derated by 10°C at an elevation of
10,000 feet. For elevations between sea level and 10,000 feet, derate the maximum operating ambient
temperature linearly.
•
Ventilation Requirements: The converter module is fan cooled and utilizes front to back forced
ventilation.
•
Audible Noise: With four converter modules installed and operating, the audible noise at any point 5 feet
from any vertical surface of the Module Mounting Shelf does not exceed 68 dBA when measured with a
sound level meter conforming to ANSI S1.4.
