5. Terminal Connecting Method
In order to use the CCG series, this power supply must be connected with external components
according to Fig.51.
If it is connected to wrong terminal, the power supply will be damaged. Pay attention to each wiring.
Fig.51 Basic connection
F1 : Input Fuse
CCG series has no internal fuse.
Use external fuse to comply various Safety Standards and to improve safety.
Moreover, use fastblow type for every power supply.
Furthermore, fuse must be connected to +Vin side if Vin side is used as ground, or fuse must be
connected to Vin side if +Vin side is used as ground.
Consider margin over the actual input voltage to be used when selecting fuse. Moreover, consider
I2t fuse rating for surge current (inrush current) during line throwin.
Input Fuse Recommended Current Rating
CCG1524xxS/D : 6.3A or lower
CCG1548xxS/D : 5.0A or lower
CCG3024xxS/D : 10A or lower

C1 : External Input Capacitor
To prevent the effect of input line inductance to the power supply, connect electrolytic capacitor
between +Vin and Vin terminals.
Recommended Capacitance
CCGxx24xxS/D : 120μF or more
CCGxx48xxS/D : 47μF or more
Note) 1.Use low impedance electrolytic capacitor with excellent temperature characteristics.
(Nippon ChemiCon KZE series or equivalent)
2.When using CCG1524xxS 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.

Protection for Reversed Input Connection
Reverse input polarity would cause power supply damage. For cases where reverse connections
are possible, connect a protective diode and fuse. Use protective diode with higher voltage rating
than the input voltage, and with higher surge current rating than fuse current rating.
External Output Capacitor
This power supply is capable of operating without external output capacitor.
For case of abrupt changes in load current or the line to the load is long, operation might become
unstable. In this case, it is possible to stabilize the output voltage by attaching capacitor.
CCGS : between +Vout and Vout terminal
CCGD : between +Vout and COM terminal, Vout and COM terminal
Maximum capacitance of external output capacitor is shown in Table 51.
Note) When using 3.3V and 5V output models of CCG30S, output voltage might become unstable at
input voltage dips or short interruption on connection output capacitor. In this case, it is possible
to stabilize the output voltage by attaching input voltage retention diode and increase capacitance
of C1 as shown in Fig.53. Use input voltage retention diode with higher current rating than fuse
current rating. Moreover, choose a suitable capacitance of C1 in accordance with operating
condition.

62. Output Voltage Adjustment Range (Only CCGS)
Output voltage could be adjusted within the range described below by connecting external resistor
or variable resistor.
However, take note that power supply might be damaged when output voltage exceeds the range
described below.
When increasing the output voltage, reduce the output current accordingly so as not to exceed the
maximum output power.
Take note that when output voltage is decreased, maximum output current is until rated maximum
output current of specification.
Output Voltage Adjustment Range : ±10% of Nominal Output Voltage
6. Explanation of Functions and Precautions
61. Input Voltage Range
Input voltage range for CCG series is indicated below.
Input Voltage Range
CCGxx24xxS/D : 9 36VDC
CCGxx48xxS/D : 18 76VDC
Take note that power supply might be damaged or not meet specification when applied input voltage
which is out of specified range.
Ripple voltage(Vrpl) which results from rectification and filtering of commercial AC line is might be
included within the input voltage as shown in Fig.61.
In this case, ripple voltage must be limited within the voltage described below.
Allowable Input Ripple Voltage：2Vpp
When input ripple voltage exceed above value, the output ripple voltage might be large.
Take note that sudden input voltage change might be cause variation of output voltage transitionally.
Moreover, maximum value and minimum value of input voltage waveform must not go beyond the limit
of above input voltage range.

Output Voltage Adjustment by External Resistor or Variable Resistor (Only CCGS)
(1) In case of adjusting output voltage lower
(11) Maximum output current
In case of adjusting output voltage lower, maximum output current is until rated maximum
output current of specification.
ex)In case of CCG30xx12S
When setting 12V Model to 10.8V output, maximum output power = 10.8V×2.5A = 27W.
(12) External resister connecting method
Connect an external resistor or variable resister Ra between TRM and +Vout terminal.
To prevent the effect of noise or other, connect as short as possible because TRM terminal is
relatively high impedance.
Please refer to Table 61 when adjusting output voltage.
Output Voltage：Vout(V), External Resistor Value：Ra(kΩ)
Output voltage could be adjusted within the 10% of nominal output voltage
by external resistor Ra.
