3.4.2 Remote Current Programming by Voltage Source
The DC voltage source is connected between Pin 19 (IPRG_VSOUR) and the return Pin
18 (RTN_PRG) and Analog Reference source is selected as Voltage from the front
Panel. Refer to Figure 3-99.
The Full-Scale voltage value can be modified to any voltage between 2V to 10V from
front panel screen, refer to Section 3.1.8.3. Default FSC voltage value is 10V, where
10V corresponds to 100% output current. The corresponding voltage-programming
coefficients for output current are (100% rated output current) / FSC VDC. This produces
transfer functions for output current, as follows:
Iout = Vdc * (100% rated output current) / 10 VDC), with Vdc in volts, or
Iout = Vdc * (100% rated output current) / FSC VDC), with Vdc in volts.
