• The FNP600/850/1000 power factor corrected (PFC) front ends

• The FNP600/850/1000 power factor corrected (PFC) front ends
The FNP600/850/1000 power factor corrected (PFC)
front ends provide (depending on model) either a 12
VDC or a 48 VDC output for telecom, datacom, and
other distributed power applications. Their small 1U by
2U size allows for configurations of either height in hotswap redundant systems while their internal fan and
cooling design permits wide use with reliable operation.
Status is provided with front panel LEDs, logic signals,
and via the I2C management interface bus. In addition,
the I2C bus can enable the power supply, control fan
speed, and on the 12 VDC models it allows for adjusting
the output voltage from 7 to 12 VDC. This powerful
feature allows the same power supply to be used in
various applications where bus voltages driving isolated
dc-dc converters and POL regulators may be different.

FNP850-12 model has airflow direction from
front-to-rear or from rear-to-front (-12R model)
ON/OFF Enable switch - shuts OFF Vo1; Vaux and
fan are operational.
Also, the FNP850-12R is uniquely designed with airflow
from the rear of the power supply to the front. This
airflow direction supports those critical applications
where space limitations and/or higher ambient
temperatures near the rear of the rack system, prohibit
the discharge of higher temperature airflow from regular
front-to-rear cooled power supplies.
The FNP600/850/1000's meet international safety
requirements and are CE marked to the Low Voltage
Directive (LVD).

OT/Fan Fail is an open-collector signal with 20-mA pull-down. High signal indicates a normal operating condition.
Output will go low at least 100 ms before OT condition shuts down the power supply. Internally pulled up to 5V
with a 5.1 kΩ resistor. Note. 2
FNP1000-48 overvoltage protection range is 56 V minimum and 60 V maximum.
A pull-up to 3.3V can be achieved by terminating the logic signal with a 10 kΩ resistor to logic ground.

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).
