Summary
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 inter-
national safety standards IEC/EN 60950, UL 1950, CAN/
CSA C22.2 No.950-95. Approvals pending.
The IMS 15 series of board mountable 15 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-
cations where variable input voltages or high transient
voltages are prevalent.
The circuit comprises of integrated planar magnetics and
all components are automatically assembled and solidly
soldered onto a single PCB without any wire connections.
The proprietary magnetic feedback solution ensures maxi-
mum reliability and 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 71°C in free air without using
any potting material. An extended temperature range –
40...71°C is available as an option. For extremely high vi-
bration environments the case has holes for screw mount-
ing.
Providing two wide input voltage ranges, 14...36 V DC and
36...75 V DC, the units are available with single, dual and
electrically isolated double outputs allowing the configura-
tion of output voltages from 3.3 up to 48 V DC externally ad-
justable, with flexible load distribution on dual and double
output units. A shut down input allows remote converter on/
off. Features include efficient input and output filtering with
unsurpassed transient and surge protection, low output rip-
ple and noise, consistently high efficiency over the entire
input voltage range, high reliability as well as excellent dy-
namic response to load and line changes.
