DESIGN CONSIDERATIONS
Input So urce Im ped anc e
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 m ore than
a few μH, we advise 150μF electrolytic capacitor (ESR <
0.7 Ω at 100 kHz) mounted close to the input of the
module to improve the stability.
Lay out and EMC Consi d erati ons
Delta’s DC/DC power modules are designed to operate
in a wide variety of sy stems 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 th e reference
design for an input filter tested with HA1SV12004PRFA
to meet class A in CISSPR 22.

Safety Consideratio ns
The po wer m odule must be installed in com pliance wit h
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,
GB 4943.1: 2011, 5000m if the system in which the
power module is to be used must meet safety agency
requirements.
reinforce insulation based on 110 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
hazardous voltage.
Basic insulation based on 110Vdc input is provided
between the input and the accessible metal of the module
when the accessible metal is grounding.
for the module’s output to meet SELV requirements,
so we only used the function insulation between output
and the accessible metal of the module
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.
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,
hazardo us voltage does not appe ar at the module’s
output.

http://www.deltaww.com/dcdc
P6
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.
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 5A m a ximum r a ting to be installed
in the ungr ound ed lea d. A l ower rate d fus e can b e used
based on the maximum inrush transient energy and
maximum input current.
Solder ing and Cl e aning Co ns i derati ons
Post so lder cleanin g is usu ally the f inal boar d assem bly
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 o pen frame t ype power m odules. For ass istance
on appropriate soldering and cleaning procedures,
please contact Delta’s technical support team.
FEATURES D ESCRIP TI O NS
Over-Current Protection
The modules include an internal output over-current
protection circuit, which will endure current limiting for
an unlimited duration during output overload. If the
output current exceeds the OCP set point, the m odules
will shut down, and will try to restart after
shutdown(hiccup mode). If the overload condition still
exists, the m odul e wi ll s hut do wn aga in. This restart tr ial
will continue until the overload condition is corrected.
Over-Voltage Pr ote ct ion
The modules include an internal output over-voltage
protection circuit, which monitors the voltage on the
output terminals. If this voltage exceeds the over-voltage
set point, the protection circuit will constrain the max
duty cycle to limit the output voltage, if the output
voltage continuously increases the modules will shut
down, and then restart after a hiccup-time (hiccup
mode).
Over-Temperature Protection
The over-temperature protection consists of circuitry
that provides protection from thermal damage. If the
module will shut down.The module will restart after the
temperature is within specification
.
Remote On/Off
The remote on/off feature on the module can be either
negative or posi tive lo gic. Negati ve logic turns t he m odule
on during a logic low and off during a logic high. Positive
logic turns the modules on during a logic high and off
during a logic low.
Remote on/off can be controlled by an external switch
between the on/off terminal and the Vi (-) terminal. The
switch can be an open collector or open drain. For
negative logic if the remote on/off feature is not used,
please shor t the o n/ off pi n t o Vi (-). For p os itiv e l og ic if the
remote on/off feature is not used, please leave the on/off
pin to floating.

To increase or decrease the output voltage set point,
connect an external resistor between the TRIM pin and
SENSE(+) pin or SENS E(-) pin. The T RIM pin shoul d be

The output voltage can be increased by both the remote

larger of either the rem ote sense or the trim, not the sum

The output vo ltage can be i nc reas ed b y both the remote
sense and the trim, however the maximum increase is
the larg er of e ither the rem ote se nse or the trim , not t he
sum of both.
When using remote sense and trim, the output voltage
of the m odule is usua lly increas ed, which inc reases the
power output of the module with the same output
current.
Care should be taken to ensure that the maximum
output power of the module remains at or below the
maximum rated power.
Pin fu nction
The pin was difine as follow in figure 20 ,we will explain
the pin function:
+IN, -IN .DC voltage inputs.
Gate IN . The Gate IN pin on a driver module may be
used as a logic ena ble/d isable input.When G ate IN is pul l
low (<1V,referenced to –Vin ),the module is turned off .
when Gate IN is floating (open collector) ,the module is
turned on .T he open circuit voltag e of Gate in PIN is les s
than 5V.
Gate OUT . the pulsed signal at the Gate OUT pin of a
regulating driver module is used to synchronously drive
the surge circuit in order to meet the IRA12 surge
needed. If you don’t used this function, please floating it.
+OUT, -OUT .DC voltage outputs.
T(TRIM). Provides fixed or variable adjustment of the
module output.
Trimming down. Allows output voltage of the module to
be trimm ed down, with a decrease in eff iciency .ripple as
a percent of output voltage goes up and input range
widens since input voltage dropout(loss of regulation)
moves down
Trim m ing up. Reverses the above effects.
-Sense,+Sense.Provides for locating the point of optim al
voltage regulation external to the converter.
THERMAL CONSIDERATIONS
Thermal management is an important part of the
system design. To ensure proper, reliable operation,
suffic ient cooling of the power m odule is needed o ver
the entire temperature range of the module.
Convection cooling is usually the dominant mode of
heat transf er.
Hence, the choice of equipment to characterize the
thermal performance of the power module is a wind
tunnel.
Thermal Testing Setup
Delta’s DC/DC power modules are characterized in
heated vertical wind tunnels that simulate the thermal
environments encountered in most electronics
equipment. This type of equipment commonly uses
vertically mounted circuit cards in cabinet racks in
which the power modules are mounted.
The following figure shows the wind tunnel
character ization set up. The po wer module is m ounted
on a test PWB and is vertically positioned within the
wind tunnel. The space between the neighboring PWB
and the top of the power module is constantly kept at
6.35mm (0.25’’).

Thermal Derating
Heat can be removed by increasing airflow over the
module. To enhance system reliability, the power
module should always be operated below the
maximum operating temperature. If the temperature
exceeds the m aximum module temperature, reliability
of the unit may be affected.
