• Description: Imx7/ Ims7 Dc-dc Series Data Sheet 7-watt Dc-dc Converters
• Manufacturer: Power-One

BCD20007 Rev AB
Standards and Approvals
The converters are approved by UL and TÜV according to UL
60950, CAN/CSA C22.2 No. 950-95 and IEC/EN 60950-1:2000.
The converters have been evaluated for:
The converters are subject to manufacturing surveillance in
accordance with the above mentioned standards.
Railway Applications
To comply with railway standards, all components are coated
with a protective lacquer (except option Z).
Protection Degree
The protection degree of the converters is IP 30, except open-
frame models (option Z).
Installation Instruction
Installation of the converters must strictly follow the national
safety regulations in compliance with the enclosure, 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; see Mechanical Data.
The converters should be connected to a secondary circuit.
Do not open the converter.
Ensure that a converter failure does not result in a hazardous
conditions.
To prevent excessive current flowing through the input lines in
case of a short-circuit, an external fuse specified in section
Input Fuse and Reverse Polarity Protection should be installed
in the non-earthed input supply line.
NUCLEAR AND MEDICAL APPLICATIONS - Power-One products are not designed, intended for use in, or authorized for use as critical components
in life support systems, equipment used in hazardous environments, or nuclear control systems without the express written consent of the
respective divisional president of Power-One, Inc.

Description of Options
Option Z: Open Frame
For applications, where the protection by a housing is not
necessary or in the case that the motherboard should be
cleaned and lacquered with the converter fitted.
Option G: RoHS-6
Converters with a type designation ending by G are RoHS-
compliant for all six substances.
Cleaning Agents
In order to avoid possible damage, any penetration of cleaning
fluids should be prevented, since the power supplies are not
hermetically sealed.
However, the open-frame models (option Z) leave the factory
unlacquered and may be cleaned and lacquered by the
customer, for instance together with the motherboard. Consult
Power-One for suitable cleaning agents.
Isolation
The electric strength test is performed in the factory as a
routine test in accordance with EN 50116 and IEC/EN 60950,
and should not be repeated in the field. Power-One will not
honor any warranty claims resulting from electric strength field
tests.
