The +24 VDC power supply product is labeled at +27 VDC input because the typical battery float voltage
is +27V; but generically, these power systems can be labeled +24 V and referred to as +24 VDC (see the
following figure for more information).

When the LED is off, it signals
that the +24 VDC output
voltage are within the normal
operating range. Output voltage
between the minimum and
maximum limits will not create
an output fail alarm, and output
voltages below the minimum or
above the maximum will create
an Output Fail alarm.
When you turn the power
supply on, the red LED
illuminates for two to three
seconds to test LED operation
before going off.
