Flag Signal: A status or alarm signal generated by
a power system. Often displayed as a front panel
LED or output logic signals (normally TTL/CMOS
compatible), typical signals would indicate “Power
Good”, “Power On”, “Over temperature”, etc.
Floating Output: A power supply output that is
ungrounded and not referenced to another output.
Typically, fl oating outputs are fully isolated and may
be referenced positive or negative by the user.
Outputs that are not fl oating share a common return
and as such, are referenced to one another.
