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:

5

[:]OUTPut[<channel>]:PROTection:FOLDback {?CCCVNONE}

 

Where:

 

NONE indicates foldback protection is disabled.

CCindicates 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.
