Connection in Parallel
The outputs of several units can be connected in parallel.
However, the use of a single unit with a higher power rating
is a better choice because of uneven power distribution
among the outputs connected in parallel. It is recommen-
ded to select converters to be connected in parallel with
very small output voltage differences at full load (i.e.
<
±0.5%). A decoupling diode is not required but recom-
mended.
Protection Scheme
The IMP series is continuously short circuit protected by
means of input power limitation. The unit will not be dam-
aged if started up into a short circuit. After removal of the
short circuit, it will resume normal operation.
The IMP series is also no-load proof, meaning that the
regulation is still effective with no load and the output volt-
age does not rise. However, due to component tolerances,
oscillation could occur and ripple and noise can be outside
of specified values. If the converter is used in senitive elec-
tronic circuits with no-load conditions, it is recommended to
pre-load the outputs with at least 20% of the specified nomi-
nal load.
Thermal Considerations
If a converter is operated, the relationship between the am-
bient temperature
TA and the case temperature TC depends
heavily on the conditions of operation and integration into a
system. The thermal conditions are influenced by input volt-
age, output current, airflow, temperature of surrounding
components and surfaces and the properties of the printed
circuit board. The specified maximum ambient temperature
TA max is therefore only an indicative value and under practi-
cal operating conditions, the ambient temperature
TA may
be higher or lower than this value.
Caution: The case temperature
TC measured at the
Measuring point of case temperature TC (see: Mechani-
cal Data) may under no circumstances exceed the
specified maximum value. The installer must ensure that
under all operating conditions
TC remains within the lim-
its stated in the table:
Temperature specifications.
Connection in Seriess
The outputs of one or more units can be connected in
seriess. No suppressor diodes are required. Power-One
however recommends to protect each individual output with
a Zener diode or preferably a suppressor diode, to avoid re-
verse polarity that may occur if the output voltages do not
rise simultaneously.
