DC Asterion Series Overview
M330460-01 Rev A 3-47
Full Scale voltage programming resistance can be modified from default 5kOhms to
any other value, from 2 kOhm to 10 kOhm, refer to Section 3.1.8.3. Then the transfer
function for output voltage, as follows:
Vout = R * (100% rated output voltage) / FSC kΩ), with R in kohms.
Figure 3-101. Remote Voltage Programming Using Resistance
3.5.2 Remote Voltage Programming by Voltage Source
The DC voltage source is connected between Pin 4 (VPRG_VSOUR) and the return
Pin 18 (RTN_PRG) and Analog Reference source is selected as Voltage from the front
Panel. Refer to Figure 3-102.
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 voltage. The corresponding voltage-programming
coefficients for output voltage are (100% rated output voltage) / FSC VDC. This
produces transfer functions for output voltage, as follows:
Vout = Vdc * (100% rated output voltage) / 10 VDC), with Vdc in volts, or
Vout = Vdc * (100% rated output voltage) / FSC VDC), with Vdc in volts.
