Output Protection
A short circuit placed on any dc output (between outputs or between
an output and a dc return) latches all dc outputs into a shutdown
state, with no hazardous condition to the power supply.
an output and a dc return) latches all dc outputs into a shutdown
state, with no hazardous condition to the power supply.
If an overvoltage fault occurs in the power supply, the power supply
latches all dc outputs into a shutdown state before any output
exceeds 135% of the nominal value of the power supply.
