Description

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 telecommu-

nication, where variable input voltages or high transient

voltages are prevalent.

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.

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 insulation.

Connected to a secondary circuit, these models provide SELV

outputs, even if the bus voltage at the converter input exceeds

the SELV-limit of 60 VDC. The 110I MY15 models provide

double insulation and are CE marked. They may be connected

to a rectified 110 VAC source without any further isolation

barrier.

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.
