3 - Programming the DC Source

Output Voltage
The output voltage is controlled with the VOLTage command. For example, to set the output voltage to 25
volts, use:
VOLTage 125
The dc source can be programmed to turn off its output if the output voltage exceeds a preset peak
voltage limit. This protection feature is implemented with the VOLTage:PROTection command as
explained in chapter 4.
Maximum Voltage
The maximum rms output voltage that can be programmed can be queried with:
VOLTage? MAX
Output Current
All models have a programmable current function. The command to program the current is:
CURRent <n>
where <n> is the current limit in amperes.
If the load attempts to draw more current than the programmed limit, the output voltage is reduced to keep
the current within the limit.
Maximum Current
The maximum output current that can be programmed can be queried with:
CURRent? MAX
Overcurrent Protection
The dc source can also be programmed to turn off its output if the current limit is reached. As explained in
chapter 4, this protection feature is implemented the following command:
CURRent:PROTection:STATe ON | OFF
NOTE: Use OUTP:PROT:DEL to prevent momentary current limit conditions caused by
programmed output changes from tripping the overcurrent protection.
