Safety according to IEC/EN 60950  
Summary  
Modules with input voltages up to 80 V are specially de-  
signed for secondary switched and battery driven applica-  
tions. The case design allows operation at nominal load up  
to 71°C without additional cooling.  
The PSC series of positive switching regulators is designed  
as power supply modules for electronic systems. Their ma-  
jor advantages include a high level of efficiency that re-  
mains virtually constant over the entire input voltage range,  
high reliability, low ripple and excellent dynamic response.
