The output voltage alarm is raised when the output voltage is below the low end of the minimum limit or
above the high end of the maximum limit. When the output voltage is above the high end of the minimum or
below the low end of the maximum limit, the red state is not activated.
The following table shows the –48 VDC power supply output voltage alarm ranges.

Color Description
Green The LED turns green to signal that the DC power supply input voltage is greater
than 43.5VDC at turn-on and remains green until the level of 39 VDC is reached.
Amber The LED turns amber if the power supply turns off due to low input voltage (falls
below 39VDC) and indicates that a hazard (voltage on the terminal block) is still
present. The LED remains amber and is active until around 20 V +/-5 V. If the
input is below 15 V, the LED is not illuminated
Green The LED turns green when all fans are operational.
Red The LED turns red when a fan failure is detected.
Red When the LED is off, it signals that the DC output voltage is within the normal
operating range. Output voltage between the minimum limit and maximum limit
will not create an Output Fail alarm, but output voltages below the minimum limit
or above the maximum limit will create an Output Fail alarm.
Led turns red to indicate that the DC output is out of the specified range.
When you turn on the power supply, the LED turns red for two to three seconds to
test the LED operation before going off.
Minimum Maximum
10.0-11.2 V 12.8-13.8 V
