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.
If the metal baseplate is grounded
,
one Vi pin
and one Vo pin shall also be grounded.
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.
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.
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 10A
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.
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 are
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.
DESIGN CONSIDERATIONS
Input Source Impedance
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
μ
H, we advise adding a 10 to 100
μ
F electrolytic
capacitor (ESR < 0.7
at 100 kHz) mounted close to the
input of the module to improve the stability.
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
to release.
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,
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.
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.
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:
