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 0.1seconds are allowed.).
The default value is 0.5 seconds.
