Resistor Mode
Ext-Ctrl Setup
5v-M 5v/5k-P R-P off
Pin 20 and Pin 13 (GND wire) can be connected to a resistor for setting the output voltage
value of the power supply.
To set the 10V/10KΩ or 5V/5KΩ external analog setting range, open the MENU (Menu)
→ CONFIG (Configure) → Ext-Ctrl (External Analog Control).
Ext-Ctrl Setup
Press the Right Key to select 5v/5k-P (or 10v/10k-P). Press the Up/Down Key to select
within the full scale scope under 10V/10KΩ or 5V/5KΩ program.
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 22. 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 0~10V/0~10KΩ or 0~5V/0~5KΩ. To
switch on the current setting, open the MENU (Menu) → CONFIG (Configure) →
Ext-Ctrl (External Analog Control). Press the Right Key to select V-P (or R-P). Press the
Up/Down Key to select the voltage mode or resistor mode.
Voltage Mode
OFF
Ext-Ctrl Setup
Under the voltage mode, the user can set the voltage output value of the power supply
through Pin 22.
