C1 : External Input Capacitor
To prevent the effect of input line inductance to the power supply, connect electrolytic capacitor
bVin and -Vin terminals.
Recommended Capacitance
CCGxx-24-xxS/D : 120μF or more
CCGxx-48-xxS/D : 47μF or more
Note) 1.Use low impedance electrolytic capacitor with excellent temperature characteristics.
(Nippon Chemi-Con KZE series or equivalent)
2.When using CCG15-24-xxS below -10
℃
ambient temperature, connect more than two
recommended capacitor in parallel to reduce ESR.
3.When input line inductance becomes excessively high due to insertion of choke coil,
operation of the power supply could become unstable. For this case, increase capacitance
of electrolytic capacitor more than recommended capacitance.
4.When steeply to open the input line by using the relay etc. when the power supply is operating,
there is possibility of the power supply restarts due to the power input voltage rises.
It is influenced by the impedance characteristics of pattern on printed circuit board, C1 and choke
coil etc.
Please use it on the actual machine sufficiently.
