Operating Temperature

For the operating temperature ranges at various altitudes of AC and DC power supply module powered switches, see Table 1.

Storage Temperature

-40 to 158°F (-40 to 70°C)

Relative Humidity Operating and Nonoperating Noncondensing

5 to 96% noncondensing

Altitude

16,400 ft. (5,000 meters)

MTBF

Calculated MTBF must be greater than 300,000 using Telcordia SR-332, Method 1, Issue 3. Demonstrated MTBF is 500,000 hr (with 90% confidence level).

EMI and EMC Compliance

“AC OK”: Input power to the power supply is OK

“PS OK”: Output power from the power supply is OK

Safety Compliance

For the operating temperature ranges at various altitudes of AC and DC power supply module powered switches, see Table 1.
