DESIGN CONSIDERATIONS  
Input Source Impedance  
Š
Š
Š
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 10µF to 100µF electrolytic  
capacitor (ESR < 0.7 Ω 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, the output must  
be also grounded.  
Š
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.  
Layout and EMC Considerations  
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 compliance design. Application notes to  
assist designers in addressing these issues are pending  
release.  
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.  
The power module has extra-low voltage (ELV) outputs  
when all inputs are ELV.  
Safety Considerations  
The power module must be installed in compliance with  
the spacing and separation requirements of the  
end-user’s safety agency standard, i.e., UL60950-1,  
CAN/CSA-C22.2, No. 60950-1 and EN60950-1+A11 and  
IEC60950-1, 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 30A 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:
