DESIGN CONSIDERATIONS

Safety Considerations

Input Source Impedance

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,

CSA C22.2 NO. 60950-1 2nd and IEC 60950-1 2nd :

2005 and EN 60950-1 2nd: 2006+A11+A1: 2010. if the

system in which the power module is to be used must

meet safety agency requirements.

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 33 to 100 µF electrolytic

capacitor (ESR < 0.7 Ω at 100 kHz) mounted close to the

input of the module to improve the stability.

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.

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. Below is the reference

design for an input filter tested with Q48SK11049XXXX

to meet class B in CISSPR 22.

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:

The input source must be insulated from the ac

mains by reinforced or double insulation.

The input terminals of the module are not operator

accessible.

Schematic and Components List

Vin(+) Vo(+)

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.

Cin

Vin

CY2

Vin(-) Vo(-)

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.

Cin is 100uF*2 low ESR Aluminum cap;

CX is 2.2uF ceramic cap;

CY1 are 10nF ceramic caps;

CY2 are 10nF ceramic caps;

CY is 1nF ceramic cap;

The power module has extra-low voltage (ELV) outputs

when all inputs are ELV.

L1 is common-mode inductor, L1=0.53mH;

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

Fast-acting 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.

Test Result

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.

48V Vin, Full Load

Yellow line is quasi peak mode;

Blue line is average mode.
