VOLTage:PROTection
Phase Selectable
This command sets the overvoltage protection (OVP) level of the AC source. If the peak output
voltage exceeds the OVP level, then the AC source output is disabled and the Questionable
Condition status register OV bit is set (see Section 7 under Programming the Status and Event
Registers). An overvoltage condition can be cleared with the OUTPut:PROTection:CLEar
command after the condition that caused the OVP trip is removed. The OVP always trips with zero
delay and is unaffected by the OUTPut:PROTection:DELay command.

Phase Selectable
This command sets the voltage range of the AC source. Two voltage ranges are available: a 150
volt range and a 300 volt range. Sending a parameter greater than 150 selects the 300 volt range,
otherwise the 150 volt range is selected.
When the range is set to 150, the maximum rms voltage that can be programmed for a sine wave
is 150 volts. For other waveshapes, the maximum programmable voltage may be different,
depending on the waveform crest factor.
The VOLTage:RANGe command is coupled with the CURRent command. This means that the
maximum current limit that can be programmed at a given time depends on the voltage range
setting in which the unit is presently operating. Refer to chapter 4 under "Coupled Commands" for
more information.
A user settable delay may be inserted between dropping the output voltage to zero and changing
the range relay state. See the “PONSetup:RELay” command for details. Your application program
should allow for this delay. (default is 0.1 sec or 100 msec).
