CAUTION: This power module is not internally fused. An input line fuse must always be used.

This power module can be used in a wide variety of applications, ranging from simple standalone operation to an

integrated part of sophisticated power architectures. To preserve maximum flexibility, internal fusing is not included,

however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies

require a time-delay fuse with a maximum rating of 8 A (see Safety Considerations section). Based on the

information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a

lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information.

EVW010A0B Series Power Modules

Design Considerations

Input Filt ering

The power module should be connected to a low
ac-impedance source. Highly inductive source
impedance can affect the stability of the power
module. For the test configuration in Figure 7 a 33­100μF electrolytic capacitor (ESR<0.1 at 100kHz),
mounted close to the power module helps ensure the
stability of the unit. Consult the factory for further
application guidelines.

Safety Considerations

For safety-agency approval of the system in which the
power module is used, the power module must be
installed in compliance with the spacing and
separation requirements of the end-use safety agency
standard, i.e., UL 60950-1-3, CSA C22.2 No. 60950­00, and VDE 0805:2001-12 (IEC60950-1).

If the input source is non-SELV (ELV or a hazardous
voltage greater than 60 Vdc and less than or equal to
75Vdc), for the module’s output to be considered as
meeting the requirements for safety extra-low voltage
(SELV), all of the following must be true:

 The input source is to be provided with reinforced

insulation from any other hazardous voltages,
including the ac mains.

 One V

pin and one V

IN

pin are to be

OUT

grounded, or both the input and output pins are
to be kept floating.

 The input pins of the module are not operator

accessible.

 Another SELV reliability test is conducted on the

whole system (combination of supply source and
subject module), as required by the safety
agencies, to verify that under a single fault,
hazardous voltages do not appear at the
module’s output.

Note: Do not ground either of the input pins of the

module without grounding one of the output
pins. This may allow a non-SELV voltage to
appear between the output pins and ground.

The power module has extra-low voltage (ELV)
outputs when all inputs are ELV.

All flammable materials used in the manufacturing of
these modules are rated 94V-0, or tested to the
UL60950 A.2 for reduced thickness.

For input voltages exceeding –60 Vdc but less than or
equal to –75 Vdc, these converters have been
evaluated to the applicable requirements of BASIC
INSULATION between secondary DC MAINS
DISTRIBUTION input (classified as TNV-2 in Europe)
and unearthed SELV outputs.

The input to these units is to be provided with a
maximum 8 A time-delay fuse in the ungrounded lead.

Feature Description

Remote On/Off

Two remote on/off options are available. Positive logic
turns the module on during a logic high voltage on the
ON/OFF pin, and off during a logic low. Negative logic
remote On/Off, device code suffix “1”, turns the
module off during a logic high and on during a logic

For positive logic, leave the ON/OFF pin open.

For negative logic, short the ON/OFF pin to V

IN

Remote Sense

Remote sense minimizes the effects of distribution
losses by regulating the voltage at the remote-sense
connections (See Figure 11). The voltage between
the remote-sense pins and the output terminals must
not exceed the output voltage sense range given in
the Feature Specifications table:

[V

(+) – VO(–)] – [SENSE(+) – SENSE(–)]  0.5 V

O

Although the output voltage can be increased by both
the remote sense and by the trim, the maximum
increase for the output voltage is not the sum of both.
The maximum increase is the larger of either the
remote sense or the trim.

The amount of power delivered by the module is
defined as the voltage at the output terminals
multiplied by the output current. When using remote
sense and trim, the output voltage of the module can
be increased, which at the same output current would
increase the power output of the module. Care should
be taken to ensure that the maximum output power of

threshold, V

Once operating, the module will continue to operate
until the input voltage is taken below the undervoltage
turn-off threshold, V

Overtemperature Protection

To provide protection under certain fault conditions,
the unit is equipped with a thermal shutdown circuit.
The unit will shutdown if the thermal reference point
Tref (Figure 13), exceeds 150
thermal shutdown is not intended as a guarantee that
the unit will survive temperatures beyond its rating.
The module can be restarted by cycling the dc input
power for at least one second or by toggling the
remote on/off signal for at least one second. If the
auto-restart option (4) is ordered, the module will
automatically restart upon cool-down to a safe
temperature.

Output Overvoltage Protection

The output over voltage protection scheme of the
modules has an independent over voltage loop to
prevent single point of failure. This protection feature
latches in the event of over voltage across the output.
Cycling the on/off pin or input voltage resets the
latching protection feature. If the auto-restart option
(4) is ordered, the module will automatically restart
upon an internally programmed time elapsing.

Overcurrent Protection

To provide protection in a fault (output overload)
condition, the unit is equipped with internal
current-limiting circuitry and can endure current
limiting continuously. At the point of current-limit
inception, the unit enters hiccup mode. If the unit is
not configured with auto–restart, then it will latch off
following the over current condition. The module can
be restarted by cycling the dc input power for at least
one second or by toggling the remote on/off signal for
at least one second. If the unit is configured with the
auto-restart option (4), it will remain in the hiccup
mode as long as the overcurrent condition exists; it

The voltage between the Vo(+) and Vo(–) terminals
must not exceed the minimum output overvoltage
protection value shown in the Feature Specifications
table. This limit includes any increase in voltage due
to remote-sense compensation and output voltage
set-point adjustment trim.

Although the output voltage can be increased by both
the remote sense and by the trim, the maximum
increase for the output voltage is not the sum of both.
The maximum increase is the larger of either the
remote sense or the trim. The amount of power
delivered by the module is defined as the voltage at
the output terminals multiplied by the output current.
When using remote sense and trim, the output
voltage of the module can be increased, which at the
same output current would increase the power output
of the module. Care should be taken to ensure that
the maximum output power of the module remains at
or below the maximum rated power (Maximum rated
power = V

O,set

x I

O,max

).

Thermal Considerations

The power modules operate in a variety of thermal
environments; however, sufficient cooling should be
provided to help ensure reliable operation.

Considerations include ambient temperature, airflow,
module power dissipation, and the need for increased
reliability. A reduction in the operating temperature of
the module will result in an increase in reliability. The
thermal data presented here is based on physical
measurements taken in a wind tunnel.

The thermal reference point, T
specifications for open frame modules is shown in
Figure 13. For reliable operation this temperature
should not exceed 122

Through-Hole Soldering Information

The RoHS-compliant (Z codes) through-hole products
use the SAC (Sn/Ag/Cu) Pb-free solder and RoHS­compliant components. The RoHS-compliant with
lead solder exemption (non-Z codes) through-hole
products use Sn/Pb solder and RoHS-compliant
components. Both non-Z and Z codes are designed to
be processed through single or dual wave soldering
machines. The pins have an RoHS-compliant finish
that is compatible with both Pb and Pb-free wave
soldering processes. A maximum preheat rate of
3

C/s is suggested. The wave preheat process

should be such that the temperature of the power
module board is kept below 210
the recommended pot temperature is 260
Pb-free solder pot is 270

C. For Pb solder,

C, while the

C max. Not all RoHS-

compliant through-hole products can be processed
with paste-through-hole Pb or Pb-free reflow process.
If additional information is needed, please consult with
your Lineage Power representative for more details.

Surface Mount Information

Pick and Place

The EVW010A0B modules use an open frame
construction and are designed for a fully automated
assembly process. The modules are fitted with a
label designed to provide a large surface area for pick
and place operations. The label meets all the
requirements for surface mount processing, as well as
safety standards, and is able to withstand reflow
temperatures of up to 300

o

C. The label also carries

Figure 20. Pick and Place Location.

Nozzle Recommendations

The module weight has been kept to a minimum by
using open frame construction. Even so, these
modules have a relatively large mass when compared
to conventional SMT components. Variables such as
nozzle size, tip style, vacuum pressure and placement
speed should be considered to optimize this process.
The minimum recommended nozzle diameter for
reliable operation is 6mm. The maximum nozzle outer
diameter, which will safely fit within the allowable
component spacing, is 9 mm.

Oblong or oval nozzles up to 11 x 9 mm may also be
used within the space available.

Reflow Soldering Information

The surface mountable modules in the EVW family
use our newest SMT technology called “Column Pin”
(CP) connectors. Figure 21 shows the new CP
connector before and after reflow soldering onto the
end-board assembly.

Figure 21. Column Pin Connector Before and After

The CP is constructed from a solid copper pin with an
integral solder ball attached, which is composed of
tin/lead (Sn/Pb) solder for non-Z codes, or Sn/Ag/Cu
(SAC) solder for –Z codes. The CP connector design
is able to compensate for large amounts of co­planarity and still ensure a reliable SMT solder joint.
Typically, the eutectic solder melts at 183
solder) or 217-218
and subsequently wicks the device connection.
Sufficient time must be allowed to fuse the plating on
the connection to ensure a reliable solder joint. There
are several types of SMT reflow

technologies currently used in the industry. These
surface mount power modules can be reliably
soldered using natural forced convection, IR (radiant
infrared), or a combination of convection/IR.

The following instructions must be observed when
SMT soldering these units. Failure to observe these
instructions may result in the failure of or cause
damage to the modules, and can adversely affect
long-term reliability.

Pb-free Reflow Profile

Power Systems will comply with J-STD-020 Rev. C
(Moisture/Reflow Sensitivity Classification for
Nonhermetic Solid State Surface Mount Devices) for
both Pb-free solder profiles and MSL classification
procedures. This standard provides a recommended
forced-air-convection reflow profile based on the
volume and thickness of the package (table 4-2). The
suggested Pb-free solder paste is Sn/Ag/Cu (SAC).
The recommended linear reflow profile using
Sn/Ag/Cu solder is shown in Fig. 24.

Tin Lead Soldering

300

The recommended linear reflow profile using Sn/Pb
solder is shown in Figure 22 and 23. For reliable
soldering the solder reflow profile should be
established by accurately measuring the modules CP
connector temperatures.

MSL Rating

The EVW010A0B modules have a MSL rating of 2A.

Storage and Handling

The recommended storage environment and handling
procedures for moisture-sensitive surface mount
packages is detailed in J-STD-033 Rev. A (Handling,
Packing, Shipping and Use of Moisture/Reflow
Sensitive Surface Mount Devices). Moisture barrier
bags (MBB) with desiccant are required for MSL
ratings of 2 or greater. These sealed packages
should not be broken until time of use. Once the
original package is broken, the floor life of the product
at conditions of

 30°C and 60% relative humidity

varies according to the MSL rating (see J-STD-033A).
The shelf life for dry packed SMT packages will be a
minimum of 12 months from the bag seal date, when
stored at the following conditions: <40°C, < 90%
relative humidity.

Post Solder Cleaning and Drying
Considerations

Post solder cleaning is usually the final circuit-board
assembly process prior to electrical board testing. The
result of inadequate cleaning and drying can affect
both the reliability of a power module and the
testability of the finished circuit-board assembly. For
guidance on appropriate soldering, cleaning and

drying procedures, refer to Lineage Power Board
