Description
The IMX7/IMS7 Series of board-mountable 7 Watt DC-DC
converters have been designed according to the latest industry
requirements and standards. The converters are particularly
suitable for use in mobile or stationary applications in
transport, railways, industry, or telecom, where variable input
voltages or high transient voltages are prevalent.
Covering a total input voltage range from 8.4 V up to 150 V with
six different types, the converters are available with single and
electrically-isolated double outputs from 3.3 up to 48 V with
flexible load distribution on double outputs. A shutdown input
allows remote on/off.
Features include efficient input and output filtering with good
transient and surge protection, low output ripple and noise,
consistently high efficiency over the entire input voltage range,
and high reliability as well as excellent dynamic response to
load and line changes.
The converters provide supplementary insulation with SELV
outputs as for instances required in battery-supported
systems, where the bus voltage may exceed the SELV limit of

60 V. The converters have been approved by TÜV and UL. In
addition, 70IMX7 and 110IMX7 models are CE-marked.
The circuitry is comprised of integral planar magnetics. All
components are automatically assembled and securely
soldered onto a single PCB without any wire connections.
Magnetic
repeatability in the control loop over all operating conditions.
Careful considerations of possible thermal stresses ensure the
absence of hot spots, providing long life in environments,
where temperature cycles are a reality. The thermal design
allows operation at full load up to an ambient temperature of
85 °C in free air without using any potting material. For
extremely high vibration environments the case has holes for
screw mounting.
Several options, such as open-frame, provide a high level of
application-specific engineering and design-in flexibility.
