Description
1 110IMY15
models
The IMX15, IMS15, 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.
provide SELV outputs, even if the bus voltage at the converter
input exceeds the SELV-limit of 60 VDC. The 110IMY15
models provide double insulation and are CE marked. They
may be connected 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
different models, the converters are available with single and
electrically-isolated double outputs from 3.3 up to 48 V,
externally adjustable, with flexible load distribution on double-
output models. A shutdown input allows for remote on/off.
The circuitry is comprised of integrated planar magnetics. 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 con-
sideration of possible thermal stress ensures the absence of
hot spots providing long life in environments, where
temperature cycles are frequent. The thermal design allows
operation at full load up to an ambient temperature of 71 °C in
free air without using any potting material. For extremely high
vibration environments the case has holes for screw mounting.
Features include efficient input and output filtering and
consistently high efficiency over the entire input voltage range,
high reliability, and excellent dynamic response to load and
line changes.
The converters have been approved by CSA. 20IMS/20IMX15
and 40IMS/40IMX15 models provide supplementary in-
sulation. Connected to a secondary circuit, these models
