Power derating

Derating may be necessary at high ambient temperature or when operating at a great height above sea level. Continuous forces are affected by the reduction.

Ambient temperature

f_T = Temperature utilization factor

t_A = Ambient temperature in °C

Calculation of the power data when exceeding the specified temperature limit > 40°C:

F_{CA_red} = F_C x f_T

Installation altitude

f_H = Altitude utilization factor

h = Altitude in meters

Calculation of the performance data if the installation altitude exceeds 1000 m:

F_{CA_red} = F_C x f_H

Ambient temperature and installation altitude

Calculation of the power data when exceeding the specified limits:

Ambient temperature > 40°C and installation altitude > 1000 m above sea level:

F_{CA_red} = F_C x f_T x f_H
