Operation

Power Supply Operation

Other protection mechanisms designed to protect the power supply are:

•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.

Set Shutdown Recovery for AC Off

There are two options for AC Off (ACO) and Over-Temperature protection (OTP):

•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.

AC Off The user has the option of setting whether the AC Off protection mechanism is Protection latched or automatically resumes operation.

SENSe:VOLT:AC:PROT:LATCH {ON1OFF0}

Where:

•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.

The default value is OFF.

To query if AC Off has tripped:

SENSE:VOLT:AC:PROT:TRIP?

Over The user has the option of setting whether the OTP mechanism is latched or Temperature automatically resumes operation.

Protection

SENSe:TEMP:PROT:LATCH {ON1OFF0}

The default value is ON.

To query if OTP has tripped:

SENSE:TEMP:PROT:TRIP?
