Pmax = Maximum power available with varying loads for an unlimited number of hours. The average power output during a 24 h period of operation must not exceed 80% of the declared pnme power between the prescribed maintenance intervals and at standard environmental conditions. A10% overload is permissible for 1 hour every 12 hours of operation.
Test conditions = 25 [°C] air température, 100 [kPA] atmospheric pressure, 30% relative humidity.
