Configure Other Protection Mechanisms
Fold Protection
Fold protection causes the supply to shut down if the selected regulation mode is
entered. A delay time may be specified as well.
To set the fold mode:
OUTP:PROT:FOLD {CC|CV|CP|NONE}
Where:
NONE indicates fold 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.
CP indicates the supply will shut down due to constant power.
The default value is NONE.
To set the fold delay:
OUTP:PROT:FOLD:DEL <delay_time>
Where:
<delay_time> is a value in the range of 0–60 seconds.
Units may be specified as “ms” (milliseconds) “s” (seconds), or “min” (minutes).
If no units are specified, the default seconds are assumed. (Increments of 0.1s are
allowed.) The default value is 0.5 second.
Over Temperature Protection
The user has the option of setting whether the over temperature protection (OTP)
mechanism is latched or automatically resumes operation. (The trip levels are
internally set and cannot be changed by the user.)
SENSE:TEMP:PROT:LATCH {ON|1|OFF|0}
Where:
ON or 1 means the supply will be latched in shutdown if OTP is tripped, until the
user clears the alarm and re-enables the output.
and OFF or 0 means the supply will automatically resume operation when the
temperature drops to below the trip level.
The default value is ON.
To query if OTP has tripped:
SENSE:TEMP:PROT:TRIP?
