12 V Fan Supply (V3)
5V Standby
12 V/0.6 A supply, present when AC supplied, inhibit turns fan supply off.
5 V/2 A supply, always present when AC supplied
AC OK is an open collector transistor, referenced to negative sense, providing a minimum of 3 ms warning of loss of output
regulation. The transistor is normally off when AC is healthy. See fig. 1.
AC OK/Power Fail
The inhibit high pin should be pulled below 0.4 V to switch V1 & V Fan (V3) off. Open circuit or 2-8 V maximum to switch
the output on. See fig. 2.
Inhibit
Connecting pin 9 (-01 & -02 models) of like voltage units (3 maximum) will force the current to share between the outputs.
Units share current within 10% of each other at full load. See fig. 3.
Current Share
When used in conjuction with -VF fan cover, varies the speed of the fan depending on temperature of the unit.
See longform datasheet for details.
Variable Speed Fan Control

The I C PMBus compatible interface can be used for monitoring the unit output voltage, current, internal temperature,
external 3 wire TACHO fan and run time. Adjustment of the output voltage and current limit set point and identification of
the unit model number and serial number are also possible. See longform datasheet for full details.

12 V Fan Supply (V3)
5V Standby
Compensates for 0.5 V total voltage drop
12 V/0.6 A supply, present when AC supplied, inhibit turns fan supply off.
5 V/2 A supply, always present when AC supplied
AC OK is an open collector transistor, referenced to negative sense, providing a minimum of 3 ms warning of loss of output
regulation. The transistor is normally off when AC is healthy. See fig. 4.
AC OK/Power Fail
The inhibit high pin should be pulled below 0.4 V to switch V1 & V Fan (V3) off. Open circuit or 2-8 V maximum to switch
the output on. See fig. 5.
Inhibit
Connecting pin 9 (-01 & -02 models) of like voltage units (3 maximum) will force the current to share between the outputs.
Units share current within 10% of each other at full load. See fig. 6.
Current Share
Only available for -EF models. Varies the speed of the integral fans depending input voltage, output power & ambient tem-
perature within the unit.
