– single- & dual output models:
– triple output- and B- version models:
Reduction of conducted Noise with external Capacitor
In order to meet conducted emissions EN55022-A and EN55011-A a capacitor at the input side of triple output models
and B-version models has to be installed.
Note:
C1 = Electrolytic capacitor low ESR type or
MLCC Cap for SMD (TCCR or THCR type from
Nippon Chemi-Con)
The value of C1 is between 1µF and 10
µF,
depending on the load
For 24V input models use 50V capacitor.
For 48V input models use 100V capacitor.
