Summary
The IMS 30 series of board mountable 30 Watt DC-DC con-
verters has been designed according to the latest industry
requirements and standards. The converters are particu-
larly suitable for applications in industry and telecommuni-
cation where variable input voltages or high transient volt-
ages are prevalent.
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 systems
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. Approvals pending.
The circuit comprises integrated planar magnetics and all
components are automatically assembled and soldered
onto a single PCB without any wire connections. The pro-
prietary magnetic feedback solution ensures maximum reli-
abilityand 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 ambi-
ent temperature of 71°C in free air without using any potting
material.
