Output Setting and Operation Commands

VOLTage:PROTection { <voltage> |MINimum|MAXimum}
Set the voltage level at which the overvoltage protection (OVP) circuit will trip.
If the peak output voltage exceeds the OVP level, then the power supply output
is shorted by an internal SCR. An overvoltage condition can be cleared with
the
VOLT:PROT:CLE
command after the condition that caused the OVP trip
is removed.
VOLTage:PROTection? [MINimum | MAXimum]
Query the overvoltage protection trip level presently programmed.
VOLTage:PROTection:STATe {0 | 1 | OFF | ON}
Enable or disable the overvoltage protection function. At
*RST
, this value is
set to ‘‘ON’’.
VOLTage:PROTection:STATe?
Query the state of the overvoltage protection function. The returned parameter
is ‘‘0’’ (OFF) or ‘‘1’’ (ON).
VOLTage:PROTection:TRIPped?
Return a ‘‘1’’ if the overvoltage protection circuit is tripped and not cleared or
a ‘‘0’’ if not tripped.
VOLTage:PROTection:CLEar
Cause the overvoltage protection circuit to be cleared. After this command,
the output voltage is restored to the state it was in before the protection feature
occurred and the OVP trip level remains unchanged to the value presently
programmed. Before sending this command, lower the output voltage below
the trip OVP point, or raise the OVP trip level above the output setting.
Note
that the overvoltage condition caused by an external source must be removed
first before proceeding this command.
VOLTage:RANGe {P8V* | P20V* | P35V** | P60V** | LOW | HIGH}
Select an output range to be programmed by the identifier. For example,
‘‘P20V’’ or ‘‘HIGH’’ is the identifier for the 20V/1.5A range and ‘‘P8V’’ or ‘‘LOW’’
is for the 8V/3A range (for E3646A model). At
*RST
, low voltage range is
selected.
VOLTage:RANGe?
Query the currently selected range. The returned parameter is ‘‘P8V’’ or ‘‘P35V’’
for low voltage range, or ‘‘P20V’’ or ‘‘P60V’’ for high voltage range.
