Description

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.

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.

The converters provide supplementary insulation with SELV

outputs as for instances required in battery-supported

systems, where the bus voltage may exceed the SELV limit of

Features

60 V. The converters have been approved by UL. In addition,

70IMX7 and 110IMX7 models 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

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.

Several options, such as open-frame, provide a high level of

application-specific engineering and design-in flexibility.
