Foldback Protection
Foldback protection causes the output of the power supply to shut down
if the selected regulation mode is entered and the configured delay time
expires. A delay time may be specified as well. The only way to clear
foldback is by pressing the rotary Adjust/Enter control for 3 seconds and
executing the Clear command.
Command:
[:]OUTPut[<channel>]:PROTection:CLEar
Setting the Foldback Mode
The following command will set the foldback mode. The mode selected
by the character mnemonic sent will indicate which mode will trigger
the foldback alarm to begin counting. For example, if the command is
sent with the CV mnemonic and the output is enabled with no load
attached (open circuit), the unit will operate in constant voltage mode
and the foldback counter will begin counting. If the CC mode was set
and the output was enabled with no load connected, the unit will operate
in CV mode and the foldback counter will not trigger.
To set the foldback mode, send the command:
Command:
[:]OUTPut[<channel>]:PROTection:FOLDback
{?|CC|CV|NONE}
Where:
NONE indicates foldback protection is disabled.
CC indicates the supply will shut down due to constant current
condition.
CV indicates the supply will shut down due to constant voltage.
The default value is NONE.
To set the foldback delay, send the command:
Command:
[:]OUTPut[<channel>]:PROTection:FOLDback:DELay
<delay_time>
Where:
<delay_time> is a value in the range of 0.5-50 seconds. The unit
of second is the default and no units should be used with this
parameter. (Increments of 0.1 seconds are allowed.). The default
value is 0.5 seconds.
