We usually define the generator\‘s ambient temperature to be at 40°C.

The ambient temperature should not be higher than 40°C, which is very important. If it does, the power of the generator should be decreased.

When ambient temperature is lower than 40°C, generator\‘s power could be larger than rated power. When it is higher than 40°C, the power should be modified by following factors.

Temperature(40°C)     Power factor

45                                      0.97

50                                      0.94

55                                      0.91

60                                     0.88
