Description
60950 and approved by TÜV, UL, and cUL. 70IMX4 models are
also CE-marked.
The IMX4 Series of board-mountable, 4-watt dc-dc converters
has been designed according to the latest industry
requirements and standards. The converters are particularly
suitable for use in mobile or stationary applications in
transport, industry or telecom where variable input voltages or
high transient voltages are prevalent.
A special feature is their small case size, DIL 24 with only
8.5 mm profile. The circuit is comprised of integrated planar
magnetics, and all components are automatically assembled
and solidly soldered onto a single PCB without any wire
connections. Thanks to the rigid mechanical design the
converters withstand an extremely high level of shock and
vibrations. 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.
Covering a total input voltage range from 8.4 VDC up to
121 VDC with three different types, the converters are
available with single and dual outputs from 3.3 up to 24 VDC
with flexible load distribution on dual outputs. Features include
efficient input and output filtering with unsurpassed transient
and surge protection, low output ripple and noise, consistently
high efficiency over the entire input voltage range, high
reliability as well as excellent dynamic response to load and
line changes.
Several options as open-frame or an alternative industrial
pinout provide a high level of application-specific engineering
and design-in flexibility.
The converters exhibit basic insulation and are designed and
built according to the international safety standards IEC/EN
