ETP48400-C3B5

Environmental conditions

Operating temperature

–40°C to +65°C (When the ambient temperature is between –33°C and +55°C, the power system works properly. When the ambient temperature is greater than 55°C and less than or equal to 65°C, the output power is linearly derated to 80%. When the ambient temperature is –40°C, the power system can start properly after AC power is applied.)

Transportation temperature

–40°C to +70°C

Storage temperature

–40°C to +70°C

Operating humidity

5%–95% RH (non-condensing)

Storage humidity

5%–95% RH (non-condensing)

Altitude

0–4000 m

(When the altitude ranges from 2000 m to 4000 m, the temperature condition for high temperature derating decreases by 1°C for each additional 200 m.)
