Program 
(Voltage 
setting) 
Output voltage of analog control:   
In setting the Voltage and 10v, the input analog range 
10V voltage, and the regulated output 
voltage should be from 0 to full range;   
In setting the Voltage and 5v, the  input analog  range 
should be 0-
5V voltage, and the regulated output 
voltage should be from 0 to full range;   
In setting the Resistance and 10K, the input analog 
range should be 0-
10K resistance, and the regulated 
output voltage should be from 0 to full range;   
In setting the Resistance and 5K, the input analog range 
should be 0-
5K resistance, and the regulated output 
voltage should be from 0 to full range;   
The 10V reference voltage output by the power supply 
can be connected to a resistance subdivision for analog

Monitor 
(Voltage 
monitoring) 
The actual value from monitoring is the corresponding 
monitor voltage value. For example, when the analog 
voltage is 10V, power supply control voltage 0~80V and 
the power supply output voltage 20V, this pin will output 
2.5V voltage. Similarly, when the analog voltage is 5V, 
80V and the power supply output 
voltage 20V, this pin will output 1.25V voltage. 
Monitor   
(Current 
monitoring) 
The actual value from monitoring is the corresponding 
monitor voltage value. For example, when the analog 
voltage is 10V,  power supply control current 0~120A 
and the power supply output current 12A, this pin will 
output 1V voltage. Similarly, when the analog voltage is 
5V, control current 0~120A and the power supply output 
voltage 12A, this pin will output 0.5V voltage.

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
