EXAMPLE 1:
An AC1-24S module has an efficiency of 81%. What is themaximum ambient temperature if 100 Watts of power is needed?

 

 

 

 

EXAMPLE 2:
What would be the maximum output power
for an AC1-24S module at an ambient temperature of 50°C with an efficiency of 81%?

 

 

 

EXAMPLE 3:
At a maximum ambient temperature of
50°C and an efficiency of 81%, how could an AC1-24S module be used if 200 Watts of output power is required?
