Safety Considerations: 

 
For safety agency approval of the system in 
which the DC-DC power module is installed, 
the power module must be installed in 
compliance with the creepage and clearance 
requirements of the safety agency.  The 
isolation is basic insulation.   For 
applications requiring basic insulation, care 
must be taken to maintain minimum  
creepage and clearance distances when 
routing traces near the power module. 
 
As part of the production process, the power 
modules are hi-pot tested from primary and 
secondary at a test voltage of 1500Vdc. 
 
To

 

preserve maximum flexibility, the power 

modules are not internally fused.  An 
external input line normal blow fuse with a 
maximum value of 10A is required by safety 
agencies.  A lower value fuse can be 
selected based upon the maximum dc input 
current and maximum inrush energy of the 
power module. 
 
When the supply to the DC-DC converter is 
less than 60Vdc, the power module meets 
all of the requirements for SELV.   If the 
input voltage is a hazardous voltage that 
exceeds 60Vdc, the output can be 
considered SELV only if the following 
conditions are met: 
 
 
 
 
 
 
 

 
 
 
 

1)  The input source is isolated from the 

ac mains by reinforced insulation. 

2)  The input terminal pins are not 

accessible. 

3)  One pole of the input and one pole of 

the output are grounded or both are 
kept floating. 

4)  Single fault testing is performed on the 

end system to ensure that under a 
single fault, hazardous voltages do not 
appear at the module output.
