Description
1 70/110IMX7models
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
prevailent.
systems, where the bus voltage may exceed the SELV limit of
60 V. The models 70IMX7 and 110IMX7 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 feedback ensures maximum reliability and
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.
Covering a total input voltage range from 8.4 V to 150 V with six
different models, 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.
Several options, such as open-frame, provide a high level of
application-specific engineering and design-in flexibility.
The converters provide supplementary insulation with SELV
outputs as for instances required in battery-supported
