ETP48600-C5A6

Environmental conditions

Operating temperature

–40°C to +65°C

(When the ambient temperature ranges from –33°C to +55°C, this product 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, this product starts properly after the AC power supply is connected. There is no requirement for the output voltage waveform at startup.)

Transportation temperature

–40°C to +70°C

Storage temperature

–40°C to +70°C

Operating humidity
