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,
open the MENU ( Menu) → CONFIG ( Configure) → Ext-Ctrl ( External Analog
Control). Press the Right Key to select Voltage ( or Resistance). Press the
Up/Down 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.
Resistor Mode
Pin 21 and Pin 13 ( GND wire) can be connected to a resistor for setting the
output voltage value of the power supply.
To set the 0~5V/0~10V or 0~5KΩ/0~10KΩ external analog setting range, open
the MENU ( Menu) → CONFIG ( Configure) → Ext-Ctrl ( External Analog
Control). Press the Right Key to select Voltage ( or Resistance).
Press the Right Key to select 5V/10V or 5KΩ/10KΩ within the full scale scope.
Current Setting ( Current Program)
This function enables change of current output through external analog signal
by connecting external DC voltage ( under voltage mode) or an external resistor
( under resistor mode) to Pin 23. 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 current setting,
open the MENU ( Menu) → CONFIG ( Configure) → Ext-Ctrl ( External Analog
Control). Press the Right Key to select Voltage( or Resistance). Press the
Up/Down Key to select the voltage mode or resistor mode.
Voltage Mode
Under the voltage mode, the user can set the voltage output value of the power
supply through Pin 23.
