3.3 Remote Sensing
The +3.3V and +5V outputs shall have provisions for remote sensing to
compensate for 100mv of cable, connector & PCB trace drops. The default
+3.3V sensor shall be connected to pin 11 of Connector P1. The +5V sensor shall be
connected to pin 20 of Connector P1. The power supply shall draw no more
than 10mA through the remote sensor line to keep the DC offset voltage to a
minimum.
3.4 Remote ON/OFF(PS-ON)
PS-ON is an active low signal that turns on all of the main power rails,
including +3.3V,+ 5V,-5V,+12V & -12V power rails. When this signal is
held up by the PC board or is left open circuited, outputs of the power rails
should not deliver current and should be held at a zero potential with respect
to ground. Power should only be delivered to the rails if PS-ON signal is
held at ground potential. This signal should be held at +5VDC by a pull-up
resistor which is built in internally.
