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.
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 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
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:
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 Q36SR12019 to meet class A in
CISSPR 22.
The input source must be insulated from the ac
mains by reinforced or double insulation.
Schematic and Components List
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,
hazardous voltage does not appear at the module’s
output.
CX1=4*2.2uF/100V ceramic cap
CX2=100uF/100V electrolytic cap
Delta standard EMI filter, FL75L20
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.
Test result:
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 50A 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.
25C, 48Vin, Green line is quasi peak mode and blue line
is average mode.
Safety Considerations
The power module must be installed in compliance with
the spacing and separation requirements of the

FEATURES DESCRIPTIONS
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.
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, and enter hiccup mode.
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 hiccup mode, the module will try to restart after
shutdown. If the over current condition still exists, the
module will shut down again. This restart trial will continue
until the over-current condition is corrected.
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 floating.
Over-Voltage Protection
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 module will shut down, and enter in hiccup
For hiccup mode, the module 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.
Over-Temperature Protection
Figure 14: Remote on/off implementation
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, and enter in hiccup.
Remote Sense
Remote sense compensates for voltage drops on the
output by sensing the actual output voltage at the point
of load. The voltage between the remote sense pins
and the output terminals must not exceed the output
voltage sense range given here:
For hiccup mode, the module will try to restart after
shutdown. This restart trial will continue until the
over-temperature condition is corrected.
[Vo(+) – Vo(–)] – [SENSE(+) – SENSE(–)] ≤ 10% ×

This limit includes any increase in voltage due to
remote sense compensation and output voltage set

FEATURES DESCRIPTIONS (CON.)
If the remote sense feature is not used to regulate the
output at the point of load, please connect SENSE(+) to
Vo(+) and SENSE(–) to Vo(–) at the module.
The output voltage can be increased by both the
remote sense and the trim; however, the maximum
increase is the larger of either the remote sense or the
trim, not the sum of both.
When using remote sense and trim, the output voltage
of the module is usually increased, which increases the
power output of the module with the same output
current.
Figure 17: Circuit configuration for trim-up (increase output
voltage)
Care should be taken to ensure that the maximum
output power does not exceed the maximum rated
power.
If the external resistor is connected between the TRIM
and SENSE (+) the output voltage set point increases
(Fig. 17). The external resistor value required to obtain
a percentage output voltage change △% is defined
as:
Output Voltage Adjustment (TRIM)
To increase or decrease the output voltage set point,
connect an external resistor between the TRIM pin and
the SENSE(+) or SENSE(-). The TRIM pin should be
left open if this feature is not used.

THERMAL CURVES
(LONGITUDINAL ORIENTATION)
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.
NTC RESISTOR
Hence, the choice of equipment to characterize the
thermal performance of the power module is a wind
tunnel.
AIRFLOW
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.

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.
