Above 40° C, a linear derating of the output current above a 26 V output voltage and higher must be observed
When using circuit breakers for protection, UL approval is only possible in TN/TT line systems with grounded neutral
point. Conventional fuses are required for UL approval in line supplies with grounded line conductor.
 
Characteristics 
Derating characteristic 
For ambient temperatures > 40 °C, a linear derating for the output current must be observed 
as of 26 output voltage.
