kVA
Note: Power consumption and heat
output vary depending on the
number and type of optional
features installed and the optional
power-management features in
use.
Heat output
Ÿ
Approximate heat output in British
thermal units (Btu) per hour:
– Minimum configuration: 256 Btu/hr
(75 watts)
– Maximum configuration: 706 Btu/hr
(207 watts)
Airflow
Ÿ
Approximately 0.5 cubic meters per
minute (18 cubic feet per minute)
Acoustical noise-emission values
Ÿ
Average sound-pressure levels:
– At operator position:
- Idle: 33 dBA
- Operating: 39 dBA
– At bystander position–1 meter (3.3
ft):
- Idle: 30 dBA
- Operating: 34 dBA
Ÿ
Declared (upper limit) sound power
levels:
– Idle: 4.4 bels
– Operating: 4.9 bels
Note: These levels were measured in
controlled acoustical environments
according to procedures specified by the
American National Standards Institute
(ANSI) S12.10 and ISO 7779, and are
reported in accordance with ISO 9296.
Actual sound-pressure levels in your
location might exceed the average values
stated because of room reflections and
other nearby noise sources. The declared
sound power levels indicate an upper
limit, below which a large number of
computers will operate.
