DESIGN CONSIDERATIONS  
Input Source Impedance  
The input source must be insulated from the ac  
mains by reinforced or double insulation.  
The impedance of the input source connecting to the  
DC/DC power modules will interact with the modules and  
affect the stability. A low ac-impedance input source is  
recommended. If the source inductance is more than a  
few µH, we advise adding a 10 to 100 µF electrolytic  
capacitor (ESR < 0.7 at 100 kHz) mounted close to the  
input of the module to improve the stability.  
The input terminals of the module are not operator  
accessible.  
If the metal baseplate is grounded, one Vi pin and  
one Vo pin shall also be grounded.  
Layout and EMC Considerations  
A SELV reliability test is conducted on the system  
where the module is used, in combination with the  
module, to ensure that under a single fault,  
hazardous voltage does not appear at the module’s  
output.  
Delta’s DC/DC power modules are designed to operate in  
a wide variety of systems and applications. For design  
assistance with EMC compliance and related PWB layout  
issues, please contact Delta’s technical support team. An  
external input filter module is available for easier EMC  
When installed into a Class II equipment (without  
grounding), spacing consideration should be given to  
the end-use installation, as the spacing between the  
module and mounting surface have not been evaluated.  
compliance design.  
Application notes to assist  
designers in addressing these issues are pending  
release.  
Safety Considerations  
The power module has extra-low voltage (ELV) outputs  
when all inputs are ELV.  
The power module must be installed in compliance with  
the spacing and separation requirements of the  
end-user’s safety agency standard, i.e., UL60950,  
CAN/CSA-C22.2 No. 60950-00 and EN60950: 2000 and  
IEC60950-1999, if the system in which the power module  
is to be used must meet safety agency requirements.  
This power module is not internally fused. To achieve  
optimum safety and system protection, an input line fuse  
is highly recommended. The safety agencies require a  
normal-blow fuse with 15A maximum rating to be  
installed in the ungrounded lead. A lower rated fuse can  
be used based on the maximum inrush transient energy  
and maximum input current.  
Basic insulation based on 75 Vdc input is provided  
between the input and output of the module for the  
purpose of applying insulation requirements when the  
input to this DC-to-DC converter is identified as TNV-2 or  
SELV. An additional evaluation is needed if the source  
is other than TNV-2 or SELV.  
Soldering and Cleaning Considerations  
Post solder cleaning is usually the final board assembly  
process before the board or system undergoes electrical  
testing. Inadequate cleaning and/or drying may lower the  
reliability of a power module and severely affect the  
finished circuit board assembly test. Adequate cleaning  
and/or drying is especially important for un-encapsulated  
and/or open frame type power modules. For assistance  
on appropriate soldering and cleaning procedures,  
please contact Delta’s technical support team.  
When the input source is SELV circuit, the power module  
meets SELV (safety extra-low voltage) requirements. If the  
input source is a hazardous voltage which is greater than  
60 Vdc and less than or equal to 75 Vdc for the module’s  
output to meet SELV requirements, all of the following  
must be met:
