• Weight (with two power modules and two fan modules, calculated based on the heaviest model if multiple models are supported): 8.85 kg (19.51 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:

Relative humidity

5% RH to 95% RH, noncondensing

Altitude

< 5000 m (16404 ft.)

Noise (sound pressure, 27°C)

• Back-to-front airflow: < 45 dBA
• Front-to-back airflow: < 45 dBA
