Pin 21
REF_10V
The 10V reference voltage output by the power supply can
be connected to a resistance subdivision for analog
quantity control.

(Current
Setting)
Output current of analog quantity control:
In setting the V-PRG and 10v/10k-
P, the input analog
quantity range should be 0-10V voltage, and the regulated
output current should be from 0 to full range;
In setting the V-PRG and 5v/5k-
P, the input analog
quantity range should be 0-5V voltage, and the regulated
output current should be from 0 to full range;
In setting the R-PRG and 10v/10k-
P, the input analog
quantity range should be 0-
10K resistance, and the
regulated output current should be from 0 to full range;
In setting the R-PRG and 5v/5k-
P, the input analog
quantity range should be 0-
5K resistance, and the
regulated output current should be from 0 to full range;

Voltage
Monitor
(Voltage
monitoring)
The actual value from monitoring is the corresponding
monitor voltage value. For example, when the analog
quantity voltage is 10V, IT6512A control voltage 0~80V
and the IT6512A output voltage 20V, this pin will output
2.5V voltage. Similarly, when the analog quantity voltage
is 5V, control voltage 0~80V and the IT6512A output
voltage 20V, this pin will output 1.25V voltage.
Pin 24
Current
Monitor
(Current
monitoring)
The actual value from monitoring is the corresponding
monitor voltage value.
For example, when the analog
quantity voltage is 10V, IT6512A control current 0~60A
and the IT6512A output current 6A, this pin will output 1V
voltage. Similarly, when the analog quantity voltage is 5V,
control current 0~60A and the IT6512A output voltage 6A,
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 20. 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 voltage 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.
