Prime Rating: – For variable load applications, there is no limit to hours of use throughout the year. The average allowable output power of continuous operation for 24 hours shall not exceed 80% of the commonly used rated power.
Standby Rating: It can be used in the event of a power outage on the grid, or under test conditions, and the maximum annual use time is not more than 200 hours. The average allowable output power of 24 hours of continuous operation shall not exceed 80% of the standby rated power.
Note: Ambient temperature 25°C, altitude 1000m, relative humidity 30%. Fuel consumption rates are based on diesel density of 0.85 and according to BS2869: 1998, Class A2.
