Description
Pulled low to enable main output
Present# signal must be pulled high through a resistor to enable the output, either to the PSU 12V bias output as shown in the wiring
diagram or to an external system bias output. The external system bias should be between 3.3V (5.1K pullup resistor) and 12V (10K
pullup resistor), with pullup resistors sized proportionally for voltages in between. The Present# signal can be used to communicate
the number of power supplies in the system (operational or non-operational). The signal is low when power supply is plugged into the
system, and is pulled up high when the power supply is unplugged. Present# is a short pin that results in a fast shut down signal to
turn off the main output and discharge the output capacitors when the supply is unplugged.

NOTES
Main Output: Current share is achieved using the droop method. Nominal output voltage (12.30V) is achieved at 1A load and output voltage drops at a rate of 7.83mv per amp
increase. Startup of parallel power supplies is not internally synchronized. If more than 460W combined power is needed, start-up synchronization must be provided by using
a common PS_ON signal. To account for ±10% full load current sharing accuracy and the reduction in full load output voltage due to droop, available output power must be
derated by 15% when units are operated in parallel. Internal ORing FETs are provided.
Standby output can be tied together for redundancy but total combined output power must not exceed 30W, Internal MOSFET ORing devices are used.
