(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)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.
