AC Off: Disables the output if the AC line drops below the acceptable range.
Sense Protection: Disables the output when the internal sense circuit is tripped
by either reversed polarity at the output of the supply or a high voltage present
at the output.
Output Fail: Disables the output if the bridge circuit fails. This is a hardware
protection circuit and has no associated software controls.
Auto-Recovery: With this method, the power supply returns to its normal
operating state once the alarm condition no longer exists. For example, if there
was an over-temperature alarm and the protection was set to auto-recovery, the
power supply would return to its normal operating state once the temperature
was reduced below the alarm level.
Latched: With this method, the power supply remains in Shutdown state until
the operator manually clears the protection and manually turns the output back
on.
ON or 1 means the supply will be latched in shut down if an AC Off condition
occurs, until the user re-enables the output, and
OFF or 0 means the supply will automatically resume operation when the AC
line input returns to normal.
