Environment

Operating temperature

–40°C to +65°C

(When the ambient temperature ranges from –33°C to +55°C, the power system works properly. When the ambient temperature ranges from 55°C to 65°C, the output power linearly derates by 20%. When the ambient temperature is –40°C, the power system can start properly after the AC power supply is connected. There is no requirement on the output voltage waveform at startup.)

Transportation temperature

–40°C to +70°C

Storage temperature

–40°C to +70°C

Operating humidity

5%–95% RH (non-condensing)

Transportation humidity

5%–95% RH (non-condensing)

Storage humidity

5%–95% RH (non-condensing)

Altitude

0 m to 4000 m

When the altitude ranges from 2000 m to 4000 m, the operating temperature decreases by 1°C for each additional 200 m.

Others
