For conditions where EMI is a concern, a differ-
ent input filter can be used. Figure 4 shows an
input filter designed to reduce EMI effects. L1,
L2 is a 2mH common mode choke.
When a filter inductor is connected in series
with the power converter input, an input capac-
itor C1 should be added. An input capacitor C1
should also be used when the input wiring is
long, since the wiring can act as an inductor.
Failure to use an input capacitor under these
conditions can produce large input voltage
spikes and an unstable output.
CNT Function
Two remote on/off options are available.
Negative logic applying a voltage less than
1.2V to the CNT pin will enable the output, and
applying a voltage greater than 3V will disable
it.
Positive logic applying a voltage larger than
3V to the CNT pin will enable the output, and
applying a voltage less than 1.2V will disable it.
Negative logic, device code suffix “ N “ .
Positive logic, device code suffix nothing is the
factory-preferred.
If the CNT pin is left open, the converter will
default to “ control off ” operation in nega-
tive logic, but default to “ control on ” in
positive logic.
The maximum voltage that can be applied to
the CNT pin is 15V.
Input-Output Characteristic
Safety Consideration
For safety-agency approval of the system in
which the power module is used, the power
module must be installed in compliance with the
spacing and separation requirements of the
end-use safety agency standard, i.e., UL1950,
CSA C22.2 No. 950-95, and EN60950.
The input-to-output 1500VDC isolation is an
operational insulation. The DC/DC power mod-
