• The value of the output current must be under the definition value of
the current which is driving capacity in the DB25 pins of the power
supply. Otherwise, the power supply will be damaged.
• The maximum digital signal input voltage≤5V
• The maximum analog signal input voltage≤12V
Voltage Setting (Voltage Program)
This function enables change of voltage output through external analog signal
by connecting external DC voltage ( under voltage mode) or an external resistor
( under resistor mode) to Pin 21. To enable this function, the output control
should be under the external analog control mode. Used for controlling the
external voltage range of full-scale output voltage or the resistor can be
selected from 0~5V/0~10V or 0~5KΩ/0~10KΩ. To switch on the voltage setting,
the operations as follows:
1. Select the MENU ( Menu)→CONFIG ( Configure)→Ext-Ctrl ( External
Analog Control).
2. Press the Right Key to select Voltage ( or Resistance).
3. Press the Right/Left Key to select the voltage mode or resistor mode.
• Voltage Mode
Under voltage mode, the user can set the voltage output value of power
supply through Pin 21.
