Physical specifications - A20 desktop model Dimensions Height: 140 mm (5.5 in.) Width: 425 mm (16.7 in.) Depth: 425 mm (16.7 in.) Heat output (approximate in British thermal units (Btu) per hour: Minimum configuration: 240 Btu/hr (75 watts) Maximum configuration: 705 Btu/hr (207 watts) Weight Minimum configuration as shipped: 9.4 kg (20 lb) Maximum configuration: 11.3 kg (25.0 lb) Airflow Approximately 0.5 cubic meters per minute (18 cubic feet per minute) maximum Environment Air temperature: System on: 10° to 35°C (50° to 95° F) System off: 10° to 43° C (50° to 110° F) Maximum altitude: 2134 m (7000 ft) Note: The maximum altitude, 2134 m (7000 ft), is the maximum altitude at which the specified air temperatures apply. At higher altitudes, the maximum air temperatures are lower than those specified. Humidity: System on: 8% to 80% System off: 8% to 80% Electrical input Input voltage: Low range: Minimum: 90 V ac Maximum: 137 V ac Input frequency range: 57-63 Hz Voltage switch setting: 115 V ac High range: Minimum: 180 V ac Maximum: 265 V ac Input frequency range: 47-53 Hz Voltage switch setting: 230 V ac Input kilovolt-amperes (kVA) (approximate): Minimum configuration as shipped: 0.52 kVA Maximum configuration: 1.50 kVA Acoustical noise-emission values Average sound-pressure levels: At operator position: Idle: 38 dBA Operating: 43 dBA At bystander position - 1 meter (3.3 ft): Idle: 33 dBA Operating: 37 dBA Declared (upper limit) sound-power levels: Idle: 4.5 bels Operating: 4.8 bels Note: These levels were measured in controlled acoustical environments according to the 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 a given 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. Note: Power consumption and heat output vary depending on the number and type of optional features installed and the power-management optional features in use. Chapter 3. Physical specifications 19
