| 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 | ||
