Power Supply Operation

OVP shuts down the power supply if the protection limit is exceeded. The other options offer a choice: they shut down the power supply or issue a warning. When the protection level is set to zero, that mechanism is considered disabled. However, in the case of OVP, a hardware protection mechanism still exists.

The last protection mechanism is Fold Mode protection, when the unit will shut down if it enters the selected regulation mode for a specified period of time.

Other protection mechanisms designed to protect the power supply are:

AC Off: AC Off protection will disable the output if the AC line drops below the acceptable range.

High Temperature Alarm: A High Temperature condition will queue an alarm message when the temperature of critical internal components nears the maximum operating temperature.

Over Temperature Protection (OTP): An over temperature condition will disable the output.

Sense Protection: Sense Protection will disable 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.

Recovery options are available for AC Off and OTP.
