Control and Monitoring
Parameter
Conditions/Description
Min.
DC OK
TTL open-collector signal with active
90
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.¹
Internally pulled up to 5V with a 5.1 kΩ
resistor. Note. ²
Input Power Fail Warning
TTL open-collector signal with active
5
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.¹ Internally pulled
up to 5V with a 5.1 kΩ resistor. Note. ²
Power Supply Present
Signal
Resistance of connection to logic
ground which allows user to determine
if power supply is present. ¹
Current Share
FNP600-12:
Main output only. Difference in current
between two supplies at >10% load
value.
FNP850-12:
FNP600-48:
FNP1000-48:
Remote Sense
Total voltage compensation for cable
losses with respect to the main output.
Output Enable
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).
1 _{Also available on I}2_{C data line.}
2 _{A pull-up to 3.3V can be achieved by terminating the logic signal with a 10 kΩ resistor to logic ground.}
