(2) In case of adjusting output voltage higher
(21) Maximum output current
When increasing the output voltage, reduce the output current accordingly so as not to exceed
the maximum output power.
ex)In case of CCG30xx12S
When setting 12V Model to 13.2V output, maximum output current = 30W÷13.2V = 2.272A.
(22) External resister connecting method
Connect an external resistor or variable resister Rb 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 62 when adjusting output voltage.

Output voltage could be adjusted within the +10% of nominal output voltage
by external resistor Rb.
