Summary
The IML10 series of board mountable 10 Watt DC-DC con-
verters has been designed according to the latest industry
requirements and standards. The converters are particu-
larly suitable for use in controlled environments, in battery
supported applications in industry or telecommunications
where high power densitiy and outstanding reliability are
required.
60 V DC. They are designed and built according to the inter-
national safety standards IEC/EN 60950, UL 1950, CAN/
CSA C22.2 No.950-95 and are LGA and UL marked. Ap-
provals pending.
A special feature is their small case size, 2" × 1" with
10.5 mm profile. The circuit comprises of integrated planar
magnetics and all components are automatically assem-
bled and solidly soldered onto a single PCB without any
wire connections. Magnetic feedback ensures maximum
reliability and repeatability in the control loop over all oper-
ating conditions. High efficiency, low heat dissipation and
careful considerations of possible thermal stresses ensure
the absence of hot spots providing high reliability. The ther-
mal design allows operation at full load up to an ambient
temperature of 60°C in free air without using any potting
material. Optionally the IML 10 series is available with the
industrial C pinout or with an SMD pinout, as well as with an
extended ambient temperature range –40...60°C.
Providing 3 input voltage ranges, 8.4...16.8, 18...36 and
36...75 V DC, the units are available with single and electri-
cally isolated double outputs allowing the configuration of
output voltages from 5 up to 30 V DC, with flexible load dis-
tribution on double output units. Features include efficient
input and output filtering with transient and surge protec-
tion, low output ripple and noise, consistently high effi-
ciency over the entire input voltage range, high reliability as
well as excellent dynamic response to load and line
changes.
The converters provide supplementary insulation with
SELV outputs as e.g. required in battery supported systems
where the bus voltage may exceed the SELV limit of

Installation Instruction
Isolation
Installation of the DC-DC converters must strictly follow the
national safety regulations in compliance with the enclo-
sure, mounting, creepage, clearance, casualty, markings
and segregation requirements of the end-use application.
The electric strength test is performed as factory test in ac-
cordance with IEC/EN 60950 and UL 1950 and should not
be repeated in the field. Power-One will not honour any
guarantee claims resulting from electric strength field tests.
Connection to the system shall be made via a printed circuit
board according to: Mechanical Data.
Table 5: Electric strength test voltages, clearance and
creepage distances
The units should be connected to a secondary circuit.
Check for hazardous voltages before altering any connec-
tions.

To prevent excessive current flowing through the input sup-
ply line in case of a short-circuit across the converter input
an external fuse should be installed in a non earthed input
supply line. We recommend a fast acting fuse F3.15 for
12 IML 10 types, F2A for 24 IML 10 types and F1A for
48 IML 10 types.
Protection Degree
The protection degree of the DC-DC converters is IP 30.
Safety of operator accessible output circuit
If the output circuit of a DC-DC converter is operator acces-
sible, it shall be an SELV circuit according to IEC/EN 60950
related safety standards
Cleaning Agents
In order to avoid possible damage, any penetration of
cleaning fluids has to be prevented, since the power sup-
plies are not hermetically sealed.
The insulation concept table below shows some possible
installation configurations, compliance with which causes
the output circuit of the DC-DC converter to be an SELV cir-
cuit according to IEC/EN 60950 up to a configured output
voltage (sum of nominal voltages if in series or +/– configu-
ration) of 30 V.
Standards and approvals
All DC-DC converters are pending to be UL recognized ac-
cording to UL 1950, UL recognized for Canada to CAN/
CSA C22.2 No. 950-95 and LGA approved to IEC/EN
60950 standards.
However, it is the sole responsibility of the installer to en-
sure the compliance with the relevant and applicable safety
regulations. More information is given in: Technical Infor-
mation: Safety.
The units have been evaluated for:
• Building in
• Supplementary insulation input to output, based on their
maximum input voltage
• The use in a pollution degree 2 environment
• Connecting the input to a secondary circuit which is sub-
ject to a maximum transient rating of 1500 V
The DC-DC converters are subject to manufacturing sur-
veillance in accordance with the above mentioned UL,
CSA, EN and ISO 9001 standards.

1 The front end output voltage should match the specified input voltage range of the DC-DC converter.
2 The earth connection has to be provided by the installer according to the relevant safety standard, e.g. IEC/EN 60950.
3 The installer shall provide an approved fuse (type with the lowest rating suitable for the application) in the non-earthed input line di-
rectly at the input of the DC-DC converter (see fig.: Schematic safety concept). For UL’s purpose, the fuse needs to be UL-listed. See
also: Input Fuse.
4 Each suppressor diode should be dimensioned in such a way, that in the case of an insulation fault the diode is able to limit the output
voltage to SELV (<60 V) until the input fuse blows (see fig.: Schematic safety concept).
5 Has to be insulated from earth by basic insulation according to the relevant safety standard, based on the maximum output voltage
from the front end.

Surface mount version
Note: Precautions should be taken when reflow soldering
the SMD version. The reflow soldering instructions below
should be strictly adhered to. An inadequate soldering pro-
cess may permanently damage the converter or degrade
its performance and Power-One will not honour any gua-
rantee/warranty claims resulting from damage caused by
ignoring the soldering instructions.

Infrared soldering is not permitted.
The surface mountable version of this product is assem-
bled with high melting point solder (227°C) to ensure that
the solder joints of of the internal components do not de-
