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.

VOLTage:RANGe

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.

Note: 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.

Note: The VOLTage:RANGe command is also coupled with the OUTPUT command. A voltage

range change can only be accomplished if the output relay is open. If the output relay is closed,

sending a VOLT:RANG <n> command will generate an 824 Error and the voltage range will not

change. (Firmware 0.26 and higher only.)

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).
