Description
LED illuminates green to signal
that the –48 VDC power supply
input voltage is greater than
43.5VDC at turn-on and
remains green down to 39VDC.
The LED illuminates amber if
the power supply turns off due
to low input voltage (falls below
39VDC) and indicates that there
is still a hazard present (voltage
on the terminal block). The
LED remains amber and is
active to around 20 V +/-5 V.
The LED is not illuminated if
the input is below 15 V.
The LED illuminates s green
when all fans are operational.
The LED illuminates red when
a fan failure is detected.
When the LED is off, it signals
that the –48 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.
Led illuminates red to indicate
that the –48 VDC output is out
of the specified range.
When you turn the power
supply on, the red LED
illuminates for two to three
seconds to test LED operation
before going off.
