Safety Considerations

DESIGN 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.

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 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 E48SP3R3XXXX 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.

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.

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=0.88mH;

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.

FEATURES DESCRIPTIONS

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.

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 or latch

mode, which is optional.

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.

Vi(+)

Vo(+)

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.

Sense(+)

ON/OFF

Sense(-)

For latch mode, the module will latch off once it shutdown.

The latch is reset by either cycling the input power or by

toggling the on/off signal for one second.

Vi(-)

Over-Voltage Protection

Figure 15: Remote on/off implementation

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

mode or latch mode, which is optional.

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. 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.

[Vo(+) – Vo(–)] – [SENSE(+) – SENSE(–)] ≤ 10% × Vout

For latch mode, the module will latch off once it shutdown.

The latch is reset by either cycling the input power or by

toggling the on/off signal for one second.

This limit includes any increase in voltage due to remote

sense compensation and output voltage set point

adjustment (trim).

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, and enter in auto-restart mode or

latch mode, which is optional.

Vi(+) Vo(+)

Sense(+)

For auto-restart mode, the module will monitor the module

operation

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.

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.

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.

DS_E48SP3R340_06052012

FEATURES DESCRIPTIONS (CON.)

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.

Care should be taken to ensure that the maximum

output power does not exceed the maximum rated

power.

Output Voltage Adjustment (TRIM)

Figure 18: Circuit configuration for trim-up (increase output

voltage)

To increase or decrease the output voltage set point,

connect an external resistor between the TRIM pin and

either the SENSE(+) or SENSE(-). The TRIM pin

should be left open if this feature is not used.

If the external resistor is connected between the TRIM

and SENSE (+) the output voltage set point increases

(Fig. 19). The external resistor value required to obtain

a percentage output voltage change △% is defined

as:

Trim resistor can also be connected to Vo+ or Vo- but it

would introduce a small error voltage than the desired

value.

The output voltage can be increased by both the remote

the larger of either the remote sense or the trim, not the

sum of both.

DS_E48SP3R340_06052012

Thermal Derating

THERMAL CONSIDERATIONS

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.

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.

Hence, the choice of equipment to characterize the

thermal performance of the power module is a wind

tunnel.

THERMAL CURVES

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.

Figure 20: Temperature measurement location

The allowed maximum hot spot temperature is defined at 117℃.

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’’).
