Should a component failure occur, the power supply should not exhibit any of the 
following: 
•  Flame 
•  Excessive smoke 
•  Charred PCB 
•  Fused PCB conductor 
•  Startling noise 
•  Emission of molten material 

 

The DC output voltages shall remain within the regulation ranges shown in Table 2 when 
measured at the load end of the output connectors under all line, load, and environmental 
conditions.  The voltage regulation limits shall be maintained under continuous operation 
for any steady state temperature and operating conditions specified in Section 5.
