Set Output Protection
Seven configurable protection mechanisms are available:
OVP: Over-Voltage Protection. Factory default = 103% V
RATED
UVP: Under-Voltage Protection. Factory default = 0V (disabled)
OCP: Over-Current Protection. Factory default = 0A (disabled)
UCP: Under-Current Protection. Factory default = 0A (disabled)
OPP: Over-Power Protection. Factory default = 0W (disabled)
UPP: Under-Power Protection. Factory default = 0W (disabled)
Fold: Fold Protection. (See below.)
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.
Slave Shutdown Alarm: Slave Shutdown Alarm (12000 Watts only) will
disable the output when one of the protection mechanisms has been enacted in
the slave unit.
Recovery options are available for AC Off, OTP and Slave Shutdown.
Also, see “Status Registers” on page 4–43.
