Summary
The IMS 6 series of board mountable 6 W DC-DC convert-
ers has been designed according to the latest industry re-
quirements and standards. The converters are particularly
suitable for use in mobile or stationary applications in trans-
port, industry or telecommunications where variable input
voltages or high transient voltages are prevalent.
Covering a total input voltage range from 18 V DC up to
75 V DC.
The converters are designed and built according to the
international safety standards IEC/EN 60950, UL 1950,
CAN/CSA C22.2 No.950-95 and are LGA and UL marked.
A special feature is their small case size, DIL 24 with only
9.0 mm profile. The circuit comprises integrated planar
magnetics and all components are automatically assem-
bled and solidly soldered onto a single PCB without any
wire connections. Thanks to the rigid mechanical design the
units withstand an extremely high level of shock and vibra-
tions. Careful considerations of possible thermal stresses
ensure the absence of hot spots providing long life in envi-
ronments where temperature cycles are a reality. The ther-
mal design allows operation at full load up to an ambient
temperature of 71 C in free air without using any potting
material.
Options : SMD pinout or K-pinout, an alternative to the
standard industrial pinout, provide a high level of applica-
tion specific engineering and design-in flexibility.

04008 Reverse Polarity Protection at Input
trise The suppressor diode on the input also provides for reverse
polarity protection by conducting current in the reverse di-
rection, thus protecting the unit. An external fuse is required
to limit this current:

Inrush Current
The inrush current has been kept as low as possible by
choosing a very small input capacitance. A series resistor
may be inserted in the input line to limit this current further.

– For 24 IMS 6 a fast 0.63 A (F0.63A) fuse is recommended
– For 48 IMS 6 a fast 0.35 A (F035A) fuse is recommended
Filter recommendations for compliance with EN 55022
Electromagnetic emission requirements according to table
Input data can be achieved by adding an external capacitor
as close as possible to the input terminals.

Safety and Installation Instructions
Installation Instruction
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.
Connection to the system shall be made via a printed circuit
board according to: Mechanical Data.
The units should be connected to a secondary circuit.
Check for hazardous voltages before altering any connec-
tions.
Do not open the module.
Ensure that a unit failure (e.g. by an internal short-circuit)
does not result in a hazardous condition. See also: Safety
of operator accessible output circuit.

Input Fuse
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 F0.5A
for 24 IMS 6 and F0.315A for 48 IMS 6 types.
Standards and approvals
All DC-DC converters are UL recognized according to UL
1950, UL recognized for Canada to CAN/CSA C22.2 No.
950-95 and LGA approved to IEC/EN 60950 standards.
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.
Safety of operator accessible output circuits
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
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 46 V.
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 DC-DC converters are subject to manufacturing sur-
veillance in accordance with the above mentioned UL,
CSA, EN and ISO 9001 standards.
