Description
The IMX15 and IMY15 Series of board mountable 15-
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
telecommunication where variable input voltages or high
transient voltages are prevalent.
40IMX15 provide supplementary insulation. Connected to
a secondary circuit the 40IMX15 models provide SELV
outputs, even if the bus voltage at the converter input ex-
ceeds the SELV-limit of 60 VDC. The 110IMY15 models
provide double insulation and are CE marked. They may
be connected for example to a rectified 110 VAC source
without any further isolation barrier.
Covering a total input voltage range from 8.4 up to 150 V
with 3 different models, the units are available with
single, dual and electrically-isolated double outputs from
3.3 up to 48 V externally adjustable, with flexible load
distribution on dual and double output units. A shut down
input allows remote converter on-off. Features include
consistently high efficiency over the entire input voltage
range, high reliability and excellent dynamic response to
load and line changes.
The circuit comprises of integrated planar magnetics and
all components are automatically assembled and solidly
soldered onto a single PCB without any wire connection.
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.
The converters are designed and built according to the
international safety standards IEC/EN/UL60950 and ap-
proved by TÜV, UL and cUL. The models 20IMX15 and
