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 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.
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.
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,
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.
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 Fast-acting fuse with 20A 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 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.
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:
Š
The input source must be insulated from the ac
mains by reinforced or double insulation.
Š
The input terminals of the module are not operator
accessible.
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.

FEATURES DESCRIPTIONS
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 modules
will automatically shut down (hiccup mode).
For negative logic, if the remote on/off feature is not
used, please short the on/off pin to Vi (-). For positive
logic, if the remote on/off feature is not used, please
leave the on/off pin to floating.
The modules will try to restart after shutdown. If the
overload condition still exists, the module will shut down
again. This restart trial will continue until the overload
condition is corrected.
Over-Voltage Protection
The modules include an internal output over-voltage
protection circuit, which monitors the voltage on the
output terminals. The default OVP operation is latch
mode. Under latch mode, If this voltage exceeds the
over-voltage set point, the module will shut down and
latch off. The over-voltage latch is reset by either cycling
the input power or by toggling the on/off signal for one
second.
Also, an optional hiccup mode for OVP is available.
under hiccup mode, the modules will try to restart after
shutdown. If the over voltage condition still exists, the
module will shut down again. This restart trial will
continue until the over-voltage condition is corrected.
Figure 16: Remote on/off implementation
Output Voltage Adjustment (TRIM)
To increase or decrease the output voltage set point,
the modules may be connected with an external
resistor between the TRIM pin and either Vout1 (+) or
Vout (-). The TRIM pin should be left open if this
feature is not used.
Over-Temperature Protection
The over-temperature protection consists of circuitry
that provides protection from thermal damage. If the
temperature exceeds the over-temperature threshold
the module will shut down.
The module will try to restart after shutdown. If the
over-temperature condition still exists during restart, the
module will shut down again. This restart trial will
continue until the temperature is within specification.
Remote On/Off
The remote on/off feature on the module can be either
negative or positive logic. Negative logic turns the
module 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.
DS_H48SA48003_09292012
Figure 17: Circuit configuration for trim-up (increase output
voltage)
If the external resistor is connected between the TRIM
and sense (+) pin, the output voltage set point increases
(Fig. 17). The external resistor value required to obtain
output voltage change to Vo is defined as:
Note:Vn is normal output voltage.
Ex.When Trim-up10%,Vo is (10%+1) *Vn =1.1*48 = 52.8V
Rtrim −up =
1 − ( 2.5 − 1.2 * 48) * (52.8 / 48)
= 616.1KΩ
(52.8 / 48) − 1
8
THERMAL CONSIDERATIONS
Thermal management is an important part of the system
design. To ensure proper, reliable operation, sufficient
cooling of the power module is needed over the entire
temperature range of the module. Convection cooling is
usually the dominant mode of heat transfer.
Figure 18: Circuit configuration for trim-down (decrease
output voltage)
If the external resistor is connected between the TRIM
and sense(-), Vout decreases (Fig. 18). The external
resistor value required to obtain output voltage change
to Vo is defined as:
Note:Vn is normal output voltage.
Ex. When Trim-down 10%,Vo is Vn-10%*Vn = 48-48*0.1
= 43.2V
Rtrim−down =
2.5 * ( 43.2 / 48) − 1
= 12.5( KΩ)
1 − ( 43.2 / 48)
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
characterization setup. The power module is mounted
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’’).
PWB
FACING PWB
When using trim-up, the output voltage of the module
is usually increased, which increases 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.

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
maximum module temperature, reliability of the unit may
be affected.
