Bit Bit Weight Bit Name Description
0 1 Over VOLtage Set if the supply’s output voltage
exceeds the over-voltage trip level,
either user-specified variable trip limit,
or the fixed trip limit.
1 2 Under VOLtage Set if the supply’s output voltage is less
than the user-specified under-voltage
trip level (variable trip limit) and the
supply is in Operation state.
