3. technical description
3.1 environment
• Working temperature: -10ºC~40ºC.
• Transportation and storage: -25ºC~55ºC.
• Relative air humidity: 40ºC≤50%; 20ºC≤90%.
• The dust, acids, corrosive gases and substance in the ambient air must be lower normal level except those from welding
process.
• Altitude must be less than 1km.
• Keep good ventilation at a distance of 50cm around.
• Put it in somewhere the speed of wind not less than 1m/s.
3.2 INPUT POWER
• Power supply waveform should be sine wave and frequency fluctuations with less than +-1% of its rating.
• The fluctuations of input voltage must be lower than +-10% of the rated value.
