6-2. Output Voltage Adjustment Range (Only CCG-S)
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

Explanation of Functions and Precautions
6-1. Input Voltage Range
Input voltage range for CCG series is indicated below.
Input Voltage Range
CCGxx-24-xxS/D : 9 - 36VDC
CCGxx-48-xxS/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.6-1.
In this case, ripple voltage must be limited within the voltage described below.
Allowable Input Ripple Voltage
：
2Vp-p
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.
