Summary

The IMS 7 series of board mountable 7 Watt DC-DC con-

verters has been designed according to the latest industry

requirements and standards. The converters are particu-

larly suitable for use in industry or telecommunications

where variable input voltages or high transient voltages are

prevalent.

Providing two wide input voltage ranges, 14...36 V DC and

36...75 V DC, the units are available with single and electri-

cally isolated double outputs allowing the configuration of

output voltages from 3.3 up to 48 V DC externally adjust-

able, with flexible load distribution on double output units.

An inhibit input allows remote converter on/off.

Features include efficient input and output filtering with un-

surpassed 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.

The converters provide supplementary insulation with

SELV outputs as e.g. required in battery supported sys-

tems where the bus voltage may exceed the SELV limit of

60 V DC. They are designed and built according to the in-

ternational safety standards IEC/EN 60950, UL 1950, CAN/

CSA C22.2 No. 950-95 and are LGA and UL marked.

A special feature is their small case size, 2"

1" with

10.5 mm profile.

The circuit comprises of integrated planar magnetics and

all components are automatically assembled and solidly

soldered onto a single PCB without any wire connections.

Magnetic feedback ensures maximum reliability and

repeatability in the control loop over all operating condi-

tions. Careful considerations of possible thermal stresses

ensure the absence of hot spots providing long life in envi-

ronments where temperature cycles are a reality. The ther-

mal 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.

Optionally the IMS 7 series is available with the industrial

C pinout or open frame.
