The IE_KS-1W&IE_S-1W Series are
specially designed for applications where a
group of polar power supplies are isolated
from the input power supply in a distributed
power supply system on a circuit board.

*Test ripple and noise by “parallel cable” method. See detailed operation instructions at testing of Power
Converter section, application notes.
Note:
1. All specifications measured at TA=25°C, humidity<75%, nominal input voltage and rated output load
unless otherwise specified.

significant filtering effect. It should also be
noted that the inductance and the frequency
of the “LC” filtering network should be
staggered with the DC/DC frequency to avoid
mutual interference see (figure 1).

*Supply voltage must be discontinued at the end of short circuit duration.
In some circuits which are sensitive to noise
and ripple, a filtering capacitor may be added
to the DC/DC output end and input end to
reduce the noise and ripple. However, the
capacitance of the output filter capacitor must
proper. If the capacitance is too big, a startup
problem might arise. For every channel of
output, providing the safe and reliable

Overload Protection
Under normal operating conditions, the
output circuit of these products has no
protection against over-current. The simplest
method is to connect a self-recovery fuse in
series at the input end or add a circuit breaker
to the circuit.

APPLICATION NOTE
Requirement on output load
To ensure this module can operate efficiently and reliably, a minimum load is specified for
this kind of DC/DC converter in addition to a maximum load (namely full load). During
operation, make sure the specified range of input voltage is not exceeded, the minimum
output load is not less than 10% of the full load, that this product should never be
operated under no load!
