Physical specifications

• Dimensions (W x D x H): 442.0 mm x 420.0 mm x 43.6 mm (17.4 in. x 16.5 in. x 1.72 in.)
• Weight (with two power modules and two fan modules, calculated based on the heaviest model if multiple models are supported): 7.6 Kg (16.76 lb)

Environment parameters

Temperature

• Operating temperature: 0°C to 40°C (32°F to 104°F) at altitude of 0-1800 m (0-5906 ft.)

  NOTE:

  When the altitude is 1800-5000 m (5096-16404 ft.), the highest operating temperature reduces by 1°C (1.8°F) every time the altitude increases by 220 m (722 ft.).

• Storage temperature: -40°C to +70°C (-40°F to +158°F)

Relative humidity

5% RH to 95% RH, noncondensing

Altitude

< 5000 m (16404 ft.)

Noise (sound pressure, 27°C)

• Back-to-front airflow: < 53 dBA
• Front-to-back airflow: < 52 dBA
