& FNR-5-12G/FNR-5-48G Power Shelves Data Sheet
TTL open-collector signal with active
20-mA pull-down. Represents percent
of output voltage where signal is OK.
Below this voltage, a signal high
condition indicates an output which is
out of tolerance. Green DC OK LED on
front panel indicates normal operation.
Internally pulled up to 5V with a 5.1 kΩ
resistor. Note.
TTL open-collector signal with active
20-mA pull-down. High indicates an
input power fail. Power Fail Warning
will turn OFF green AC OK LED.
Represents the time after warning
signal before Vout drops to 95% due to
loss of input power.
up to 5V with a 5.1 kΩ resistor. Note.
Resistance of connection to logic
ground which allows user to determine
if power supply is present.
Main output only. Difference in current
between two supplies at >10% load
value.
Total voltage compensation for cable
losses with respect to the main output.
Open circuit or logic high from ENA pin
to Vo1 RTN shuts OFF Vo1; Vaux and
fan are operational. Logic low (2 mA
sink capability) or jumper will turn ON
Vo1 within 500 ms. Open circuit
voltage on enable pin is 3.3 VDC.
Externally applied voltage to the enable
pin should NOT exceed 7 VDC. Signal
is referred to as Logic Return (LRTN).
